NAME

       81voltd - Server-side implementation of the QMI IMS Data service

SYNOPSIS

       81voltd

DESCRIPTION

       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.

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.

       ModemManager errors are not communicated to the modem.
