Description

We need to select codecs.. There were multiple mails on the OpenBSC list. For GSM MO call we need to check the bearer calls and the availability of channels and then can offer different codecs. The FR vs. HR decision needs to be done early but then codec can be changed.

The MNCC protocol needs to change in many still to be defined ways. This includes:

  • NITB needs to inform which TCH/F.. TCH/H are available
  • RTP_CREATE/RTP_CONNECT needs to include AMR mode-sets
  • Need to test switching codec
  • BTS needs to support Payload2 to allow asymentric PayloadType for the same codec!
