- nathelper: fixed building of received uri when IPv6 is used.
  Credits go to Klaus Darilion <klaus.mailinglists@pernau.at>

* 2006-06-06 Daniel-Constantin Mierla <daniel@voice-system.ro>
- core: check for null passwords (on some OS strcmp crashes) - reported by
  Edgar Barbosa

* 2006-06-05 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- core: fixed bug in cleaning lump lists based on flags - this was generating
  double inserts in Branch routes or memeory leaks in Failure routes.

* 2006-06-01 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- core: fixed init of default server and client tls domains

* 2006-05-31 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- core:  bug fixed in choosing the default port: if proto is TLS and no port
  or SRV is available, use 5061 as default port for outgoing connections.
- gflags: flag range checked for script functions
- gflags: proper cleanup at module destroy
- gflags: got rid of memory allocation in fixup function
- gflags: optimized fixup function -> compute directly the bitmap

- dbtext: added support DB_BITMAP in update() - reported by Ovidiu Sas
- core: fixed linking error on solaris for utils' tools due to -lfl (reported
  by Ryan matty91@gmail.com)

* 2006-05-30 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- core: even if it has no script parameters, a function may export a fixup
  function. If, param  no. = 0, the fixup will be called with param index 0.
  If function has params, nothing is changed. The possibility to have a fixup
  function even if no param is exported is useful when checking global settings
  that may affect the behaviour of the function.
- uri_db: "db_url" module parameter may be set to empty string in orer to
  disable DB support in the module - this is needed if you want to use
  check_to() or check_from() to check the user against credentials in a non DB
  environment.
- tm: fixed branch picking algorithm - if cancelled, but not 487 replied
  received, fallback and use classical algorithm.
- tm: fixed bug in CANCEL retransmission - an implementation more closer to the
  hop by hop CANCEL processing concept
- core: - fixed bug in parsing display name in format:
  "From: token1 token2<uri>"

* 2006-05-29 Daniel-Constantin Mierla <daniel@voice-system.ro>
- dbtext: dbt_row_set_val() accepts DB_BITMAP (reported by Ovidiu Sas)

* 2006-05-29 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- avpops: memory leak fixed in avp_raw_query()
  Credits go to John Riordan <john@junctionnetworks.com>
- core: FROM / TO header paramter parsing fixed:
    1) TAG parameter must have value, but any other parameters are accepted
        without value
    2) removed the NO_PINGTEL_TAG_HACK (long time ago, pingtel phones were
        sending empty tag param in TO) - it's conflicting the RFC 3261;
  Reported by Ovidiu Sas <osas@somanetworks.com>.
- permissions: fixed crash when permission module was shutdown after an
  incomplete startup. Reported by  Elton Machado (lowgitek).
- tm: bug fixed in building ACKs for negative replies to local INVITEs. RURI
  must be the same as in INVITE and Route hdr have no send to be added.
  Thanks to Elias Baixas <elias.baixas@voztele.com> for troubleshooting the
  problem.

* 2006-05-26 Juha Heinanen <jh@tutpro.com>
- lcr: if R-URI userpart becomes empty, @ sign is not included in R-URI.

* 2006-05-25 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- postgres: bug fixed - postgres may return a row without a column value, so
  we need to double check it. Credits go to
  Arve Rasmussen <Arve.Rasmussen@iplink.no>
- auth_db: module accepts DB_STR type for credentials (dbtext beckend returns
  only DB_STR and not DB_STRING).
  Reported by Ovidiu Sas <osas@somanetworks.com>.

* 2006-05-24 Andreas Granig <andreas.granig@inode.info>
- core: heck for null-pointer before accessing Supported-flags.

* 2006-05-24 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- unixodbc: unixodbc patch wasteful memory fixes and reconnect, patch by
  Sumeet Gupta <skg1010@hotmail.com>
- uac_redirect: bug fixed - q value is also pushed into branches in order to 
  allow serial forking. Based on an original patch from
  Michael Samuel <michael.samuel@ipsystems.com.au>

* 2006-05-22 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- core: forward and send functions merged by including the protocol, host and
  port into a single parameter like [proto:]host[:port]. Aligned to t_relay()
  and t_forward() format and NAPTR lookup enabled also.
- core: applied patch from Klaus Darilion :  provides TLS client domains
  (name/socket based) and more script config capabilities
- tlsops: new module for TLS operations, patch by Klaus Darilion

* 2006-05-22 Daniel-Constantin Mierla <daniel@voice-system.ro>
- acc: null pseudo-variable values are stoared as "n/a" to keep consistency
  with acc format (reported by Juha Heinanen)

* 2006-05-19 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- avpops: branch can be used as new destinaton for avp_pushto().
    Ex: avp_pushto("$br","$avp(i:30)");  - it will push the avp directly as a
        new branch without affecting the RURI.
- acc: bugs fixed:
  ~ the "missed call" report will display as outgoing uri exactly the RURI used
    for that branch
  ~ the accounting report will display as outgoing uri the RURI of the winning
    branch
  ~ proper internally handling (set/reset) of the "missed call" flag
- acc: behaviour fix:
  ~ the "missed call" flag has effect only on the next serial fork - once
    triggered to report a missed call (a serial fork step ended), the flag is
    automatically reset by module. To catch the potential "missed call" reports
    due next serial forks, you need to re-arm the flag from failure route.
    This behaviour gives full control over what branches should be or not
    accounted as "missed calls".
- tm: branch selection algorithm centralized in a single place - more coherent
    and easier to maintain.
  ~ the selected branch in stored in a static variable to avoid multiple
    computation for same transaction (so far, each t_check_status() call was
    triggering computation of the selected branch)
  ~ TM API exports a new function for making public the selected branch (how
    the winning branch is selected must be transparent for the other modules)
  ~ fixed the branch selection algorithm - if the transaction was cancelled, the
    "487 Request cancelled" reply will have priority and it will be sent to UAC.
- usrloc: module is able to detect retransmissions based on Callid and Cseq. The
  retransmission detecton is controled via the new "cseq_delay" module
  parameter.
  REGISTER retransmissions (inside the cseq_delay interval) will not generate
  error, but they will be accepted and properly replied without any update on
  the location status.
  This solves the problem of retransmissions without having a statefull
  processing on requests.
- core:  new function added : int branch_uri2dset( str *new_uri ) ->
  moves the uri to destination for all branches and all uris are set to
  given uri; to be used to implement replication to multiple destinations
- tm: t_replicate() takes as parameter a SIP URI instead of a destination (in
  order to align the format as for append_branch() ).
- tm: t_replicate() uses the set branches to perform parallel replication to
  multiple destinations

* 2006-05-15 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- nathelper: applied patch for fixing the multiple stream handling in
  sequential requests. Patch by Laurent Schweizer <laurent.schweizer@gmail.com>

* 2006-05-13 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- rr: bug fixed in routing after a strict router
  Reported by Walter Schober <walter.schober@neotel.at>

* 2006-05-07 Daniel-Constantin Mierla <daniel@voice-system.ro>
- core: added support to manage AVP flags from configuration script
  ~ flags are 8bit long and have to specified after the AVP name type and before the semicolon, e.g., s3:rpid - string-named AVP with flags 1 and 2 set
  ~ avp naming is now $avp(name_type[flags]:name_id) - name_type = s | i;
    script_flags = 1..255
  ~ a reference to an AVP via alias is now: $avp(alias)
  ~ updated AVP API to allow flags usage

* 2006-05-05 Dan Pascu <dan@ag-projects.com>
- auth_db: Properly handle integer columns in the subscriber table when
  generating the AVPs specified by the auth_db/load_credentials module
  parameter. This fixes crahses caused by invalid memory access when a
  non-string column was specified to be loaded in load_credentials.
   With this patch, string and integer table columns are properly handled and
  will create an AVP with a string respectively an integer value depending
  on the type of the column in the subscriber table that is loaded.
  Other column types are currently not handled and will generate an error
  message in the logs if used, however if need arises they can be handled by
  converting them to a string and creating an AVP with a string value.
- core: Added missing definition for pkg_realloc if PKG_MALLOC was not defined
  and the standard libc allocation functions were used

* 2006-05-04 Klaus Darilion <klaus.mailinglists@pernau.at>
- dialog: added newly introduced parameter when registering pseudo variables

* 2006-05-03 Daniel-Constantin Mierla <daniel@voice-system.ro>

  computed to access the rigth value (reported by Dan Pascu)

* 2006-05-02 Daniel-Constantin Mierla <daniel@voice-system.ro>
- core: allow to set parameter for callback functions of extra pseudo-variables

* 2006-04-28 Juha Heinanen <jh@tutpro.com>
- lcr: applied patch by Andreas Granig that adds optional group id parameter
  to load_gws(), from_gw(), and to_gw() functions.

* 2006-04-26 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- tm: use new_uri instead of original uri in t_write().
  Credits go to Juha Heinanen <jh@tutpro.com>

* 2006-04-21 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- dialog: more dialog callbacks added: DLGCB_EARLY and DLGCB_RESPONSE_FWDED
  Patch provided by Ron Winacott <ronw@somanetworks.com>

* 2006-04-19 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- dialog: callback types renamed to avoid overlapping with some TM defines.
  Reporded by Ron Winacott <ronw@somanetworks.com>

* 2006-04-14 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- dialog: new module for dialog support
- unixodbc: leaking memory in the covert rows function; removes some deprecated
  ODBC functions; invalid cursort state on error; error reporting from ODBC;
  patch by Sumeet Gupta <skg1010@hotmail.com>

* 2006-04-13 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- core: fixed bug when using exit/return within a switch statement
- core: support for setting custom lifetime (expire time) for the TCP
  connections
- registrar: module may set for TCP connection a custom lifetime for keeping
  it open as long as the registered contact is valid.

* 2006-04-13 Daniel-Constantin Mierla <daniel@voice-system.ro>

Christian Schlatter)

* 2006-04-11 Daniel-Constantin Mierla <daniel@voice-system.ro>
- avpops: fixed avp_db_load() when loading all avps of a type (reported by
  Andreas Granig)

* 2006-04-10 Bogdan-Andrei Iancu <bogdan@voice-system.ro>

- uac: forbid from changing in auto mode only for URI, but allow it for display

* 2006-04-07 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- scripts: replaced gen_ha1 with md5sum

* 2006-04-07 Daniel-Constantin Mierla <daniel@voice-system.ro>
- siptrace: siptrace
  ~ allow to intercept the SIP messages processed by the sip server and store
  them in a database
  ~ messages are stored along with destination IP and changes made by proxy to
  the original messages
  ~ ability to send a duplicate of the message to a configurable address

* 2006-04-06 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- cpl-c: fixed bug in processing DROP / EXIT in branch route (due nested
  execution). Reported by Tavis P <tavis.lists@galaxytelecom.net>

* 2006-03-29 Juha Heinanen <jh@tutpro.com>
- core: check_dig_cred() now checks that if digest username has domain, it
  must match realm.

* 2006-03-29 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- tm: new TM callbacks added:
          TMCB_TRANS_DELETED - called when the transaction is deleted
          TMCB_REQUEST_BUILT - called just before sending out a request
- tm: callback can get more paramters via extra params
- tm: 'char * buffer' and 'int len' fields in 'struct retr_buf' merged into a
  'str' for better manipulation
- sl: callbacks added - the only event is sending a stateless reply
- nathelper: bug fixed in processing the newly added "c" flag in
  force_rtp_proxy(). Reported by Bayan Towfiq <bayan@towfiq.com>

* 2006-03-28 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- acc: bug fixed in acc with serial forking: o-uri contains the uri of the
  winning branch and not the the first one.
- unixodbc: fixed bug in function db_update() : the query string was null
  terminated only if exist 'where' parameters.
- unixodbc: appled patch to support ODBC reconnect when connection not open or
  communication link failure - by Alex Gradinar <Alex.Gradinar@cartel.md>
- tm: applied patch provided by Juha Heinanen <jh@tutpro.com> : port from
  SER of "pass_provisional_replies" TM options (pass back through unixsock
  the provisional replies and not only the final one).
  This was required in order to maintain compatbility with latest SEMS
  version.
- nathelper: added support for changing session-level SDP connection (c=) IP
  when media-description also includes connection information.
  This can be enabled by setting the "c" flag to force_rtp_proxy()
  Based on a patch sent by Bayan Towfiq <bayan@towfiq.com>

* 2006-03-24 Dan Pascu <dan@ag-projects.com>
- mediaproxy: do not print error to syslog is SDP body is missing. Return a
  different negative code instead (-2) and let the caller handle the error
  (there are cases where a missing SDP body is not an error and can be ignored).
  This also helps by avoiding the need to call a has_body() function prior
  to calling use_media_proxy(). Instead call use_media_proxy() directly and
  it will tell you if it can't find a body, but without giving an error to
  syslog

* 2006-03-20 Juha Heinanen <jh@tutpro.com>
- lcr: stripping was not done when next_gw() was called in  FAILURE_ROUTE.

* 2006-03-19 Juha Heinanen <jh@tutpro.com>
- permissions: if a trusted peer has a non-NULL tag field and if peer_tag_avp
  module parameter is defined, tag value of matching is added to AVP specified
  by peer_tag_avp as side effect of allow_trusted() call.

* 2006-03-17 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- textops: applied patch (modified) from Marc Haisenko <haisenko@comdasys.com>:
  provides new function has_body([mime])

* 2006-03-15 Jesus Rodriguez <jesusr@voztele.com>
- packaging: fix undefined symbols problems
- the HEAD branch of the CVS will keep the FreeBSD port files to build the
  last stable version. A tarball (and its checksum) is needed to build the
  port and this is not (easily) possible with current.

* 2006-03-15 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- core: xl_printf_s() has now support for nested calls - fixes in the simplest
  way the bug in uac_replace_from() when both parameters contains
  pseudo-variables. Reported by Urtho <junk@urtho.net>.
- core: bug fixed in extracting proper Route parameters after a strict router.
  Reported by Dan Pascu <dan@ag-projects.com>
- nathelper: bogus error message removed - if the contact header does not
  contain any URI, do not report it as a contact-body parse error - it may be
  a (*) body.

* 2006-03-15 Daniel-Constantin Mierla <daniel@voice-system.ro>
- core: added PUBLISH in the list of known methods

* 2006-03-14 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- uac: uac_auth() bug fixed in parsing the auth challenge - not all values are
  expected to be quoted.
- usrloc: get_contacts fifo and unixsock functions retunrn more additional info
  related to the contact:
          expires;flags;socket;methods;received?;user_agent?;path?
  values marked with ? may be missing if empty.
- statistics: new module to provide statistic variables support directly into
  the script

* 2006-03-13  Di-Shi Sun <di-shi@transnexus.com>
- osp: fixed several typos in usage.c

* 2006-03-13 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- osp: module aligned to use the RR functionality via the RR API to avoid
  mismatches between function prototypes.
- core: more hash functionality:
  1) hash support in core
      - new_hash1() and new_hash2() merged into core_hash()
      - added core_case_hash() for case insensitive hashes
      - all TM related definitions moved into TM config file
      - if hash size param is 0, the functions will return the hash id
        instead of hash entry.
  2) domain module
      - use the case insensitive hash function
  3) pdt module
      - use the case insensitive hash function
  4) permission module
      - just updated according to coe hash changes
  5) TM module
      - updated according to coe hash changes
      - TM related stuff moved localy from core hash
- registrar: fixed memory bug - build_path_vector() does not allocated memory
  for the path array (returns a static buffer), so no free is needed anymore.
  Reported by Helge Waastad <helge@smartnet.no>
- registrar: build_path_vector() use the sibling link between the headers in
  order to have a faster access to all PATH headers.

* 2006-03-09 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- tm: bug fixed in processing the failure handlers (callbacks and route); error
  cases were not properly handled.
  Reported by Matt Schulte <mschulte@netlogic.net>

* 2006-03-08 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- nathelper: several upgrades to existing functions:
   - fix_nated_sdp() may take one more param to force a specific IP instead of
        the signalling IP
   - force_rtp_proxy() accepts a new flag 's' to swap creation/confirmation
        between requests/replies (this is needed to be able to cope with SDPs
        advertised via 200OK / ACK)
   - add_rcv_param() may take as parameter a flag telling if the parameter
     should go to the contact URI or contact header; make sense if you forward
     REGISTER requests and need the registrar to save the parameter as part of
     URI.
- usrloc: bug fixed when getting all contacts - most probably the bug was
  inserted when the DB_ONLY mode was added

* 2006-03-07 Dmitry Isakbayev <isakdim@gmail.com>
 - osp: update module for:
  1. int_str casing issue, in destination.c and usage.c
  2. inculde data_lump.h in sipheader.c

* 2006-03-07 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- acc: etc/dictionary.radius contains only the OpenSER proprietary attributes
  and values; All standard (IANA registered) attributes are defined in the
  default dictionary of the radiusclient-ng library
- acc: values for Sip-Method attribute set as they are used by OpenSER. NOTE
  they overwrite the default values as defined by radiusclient-ng library.

* 2006-03-03 Daniel-Constantin Mierla <daniel@voice-system.ro>
- osp: removed dependency of textops module - append_hf() replaced with a local
  function

* 2006-03-03 Andreas Granig <andreas.granig@inode.info>
- path: new module for intermediate proxies to add Path-HFs and route
  requests according to the received-parameter of Route-HF URIs.

- registrar: support in registrar for loadbalancing using Path-HF with
  NAT-Support applied, patch by Andreas Granig <andreas.granig@inode.info>
- uac: default value for "from_restore_mode" switch to auto
- uac: new module parameter "from_passwd" - used to encrypt the RR parameter
  which contains the original FROM URI
- uac: uac_replace_from() adds the display name if not present (so far it only
  replaced it); uri is enclosed between brackets if not.
  Actually, now you can set a display name if none was present.

* 2006-03-02 Daniel-Constantin Mierla <daniel@voice-system.ro>
- $si and $sp were mistakenly changed in $Si and $Sp by previous commit
  - reverted now (reported by Thomas Gelf)

* 2006-03-02 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- uac: when performing UAC authentication, look in predefined AVPs for
  credentials before using the static set credentials (via modparam)
- uac: new module parameters for defining the AVPs to contain realm, username
  and password for authentication.
- core: new header chaining based on type - all headers of same type are linked
  together via sibling link (Ex: msg->allow points to first Allow hdr;
  msg->allow->sibling to the second Allow hdr, and so on).
- core: parser for Allow ans Supported headers updated to parse and merge the
  values from all headers. This fixes problems in REGISTER module when PATH or
  method filtering supports are used - originally only the first
  allow/supported hdr was processed, the rest of them being ignore. This was
  problem maker if a client was registering with multiple Allow hdr, for
  example - reported by Daniel Hsueh <dhsueh@somanetworks.com>.
- core: several changes into routing/scripting internal tree:
  1) allow module to export same C function with same name, but with different
     parameter number - a lot of wrapper functions will become obsolete
  
  2) keep inside the tree nodes the corresponding config line to be able to
     give a more detailed report if fixup functions fails (like line number)
  
  3) some cleanup to simplify the association between the tree actions and
     exported functions

* 2006-03-01 Daniel-Constantin Mierla <daniel@voice-system.ro>
- core: XL_RPID, XL_DIVERSION types renamed to XL_RPID_URI, XL_DIVERSION_URI

- tm:  module exports $T_branch_idx pseudo-variable refering to the index of
  the branch for which the branch_route[] is executed
- core: avp names must use i: or s: in front of IDs to avoid confusions
- core: avp alias is specified without $

* 2006-03-01 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- acc: Radius acc requests include an event time stamp (Event-Timestamp Radius
  AVP - see RFC2869). The Radius server timpstamp is not reliable since it
  contains also the delays due possible RADIUS retransmissions.
- unixodbc: several problems fixed:
  1) memory allocation size problem when converting the returned rows.
  2) use a define for the size of the static strings - avoid mem. overrides
     if changing the size
  3) more general connection cleanup (properly supported by a larger number
     of drivers)  before submitting a new query
- core: returne codes alligned (for widly used core functions) in order to
  avoid confusions
          == 0 - success
           < 0 - error
- cpl-c: applied patch from John Riordan <john@junctionnetworks.com> : provides
  NAT traversal support (via received) for the lookup CPL node.
- cpl-c: added per branch nat flags support for lookup CPL node
- auth: realm string in www/proxy challenge/authorize support pseudo variables.
  Allows dynamic realm definition in multi domain env.

* 2006-02-28 Bogdan-Andrei Iancu <bogdan@voice-system.ro>

  Daniel Hsueh <dhsueh@somanetworks.com>

* 2006-02-24 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- core: fixed parsing bug when spaces are present in non-quoted display name.
  reported by Raymond Chen <rchen@broadz.com>
- usrloc: fixed bug when insertion contacts in a new built AOR record - use
    get_ucontact() to detect contact duplicates.
    An initial REGISTER may contain several contacts and some of them may be
    identical. IF DB is used, this will lead to primary key (username, domain,
    contact URI) violation due double insert. Also un-necessary parallel fork
    to same destination is avoided.
  
    This may happen with bogus clients (I see no reason why a UAC may duplicate
    a contact in same REGISTER), so the fix is protection mechanism for the
    proxy.

* 2006-02-23 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- usrloc: new DB mode - DB-Only - no memory cache is kept, all operation being
    directly done into DB.
    Allows DB sharing between multiple proxies without the need of additional
    replication mechanism.
    Drawbacks:
          - some performance penalties due intensive DB usage
          - location watcher disabled (cannot be bind to a record into mem)
                          => PA cannot be used
          - statistics do not work since events cannot be properly been traced
            without a mem cache

* 2006-02-22 Klaus Darilion <klaus.mailinglists@pernau.at>
- core: introduction of the parameters tls_verify_server and tls_verify_client:
  allows to have different policies for incoming and outgoing TLS connections

* 2006-02-21 Daniel-Constantin Mierla <daniel@voice-system.ro>

          - replace_body()
          - replace_body_all()
          - subst_body()

* 2006-02-17 Juha Heinanen <jh@tutpro.com>

* 2006-02-16 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
- core: fixed several bugs strictly related to libssl version 0.9.8:
  1) bad record mac because of wrong SSL_OP_TLS_BLOCK_PADDING_BUG handling
     (see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338006 for more
     info ; original bug registration to libssl at
     http://www.aet.tu-cottbus.de/rt2/Ticket/Display.html?id=1204 - note, it
     requires subscription)
  2) zlib compression does work correctly anymore in multi-process env. due
     problem with mem. allocation functions. Fix: disable compression.
     (see http://www.aet.tu-cottbus.de/rt2/NoAuth/Buglist.html - again,
     subscription is required)
- core: bug fixed : return code of tcp_send() set to negative value if write()
    failed; this was preventing the proxy to generate a negative reply in case
    of connection error via TCP (TLS was affected too).
    Reported by Klaus Darilion <klaus.mailinglists@pernau.at>

* 2006-02-15 Daniel-Constantin Mierla <daniel@voice-system.ro>

  the usage of callback that may change the routing info without overlapping
  with the RR processing.
- core: applied patch from Daniel Hsueh <dhsueh@somanetworks.com> for
  SUPPORTED hdr: 1) corrects "rel100" to "100rel" (according to RFC 3262);

  (e.g., avp_check("$fu", "eq/$tu") returns true if From URI equals To URI;
  avp_write("$tU", "$avp($fU)") - writes the username in To header in the avp
  having the name the username from From header)

- acc: DB support is compiled by default
- acc: DB support disabled by default (db_url=0)

      fwd, not stored, but only timers updated)

* 2005-08-29 Bogdan-Andrei Iancu <bogdan@voice-system.ro>
