Re: Specifying channel mode for speech

Osmo-bts gets the MODE_MODIFY_REQ from OpenBSC with GSM48_CMODE_SPEECH_EFR to use for the channel mode. However, I would like to be able to specify using GSM48_CMODE_SPEECH_V1 instead (which is FR; EFR is not supported in L1). Is there an easy way to set the preferred channel mode/audio support? I didn't see anything on the VTY wiki or in the config file.

hi tom,

you may change the line 46 at mncc_builtin.c. the first entry in this array is the full rate code, the second entry is the half rate codec. (depending on the trx configuration) just change the first entry to GSM48_CMODE_SPEECH_V1.
