.TH 81VOLTD 1 "February 18 2025" "81voltd" "Server-side implementation of the QMI IMS Data service"
.SH NAME
81voltd \- Server-side implementation of the QMI IMS Data service
.SH SYNOPSIS
.B 81voltd
.SH DESCRIPTION
.B 81voltd
is a simple implementation of the IMS Data service on QMI/QRTR. It handles
the known and important requests to start and stop a connection through the
ModemManager D-Bus API, treating other requests as no operation.
The IMS Data service is mandatory to support voice call on 4G/5G mobile
network.
.SH BUGS
Stopping the implementation does not release or disconnect any bearers. This
makes it hard to debug, requiring the modem be set to low-power, then back
online.
.PP
ModemManager errors are not communicated to the modem.
