[Freeswitch-users] Limiting available codecs in bypass media mode

[Phil Quesinberry]

I'm wondering what the best way is to limit the available codecs when making
outbound bypass-media calls to the PSTN.  The scenario is as follows:
Extension phones have HD codecs including G722 enabled for the best audio
quality between extensions for internal calls.  When an outbound call is
made to the PSTN, the first-choice wholesale provider we use offers (and
seems to prefer) G722.  We'd rather ensure that G711 is used instead.
Despite the fact that G722 is not enabled for any of the codec prefs (I
grep'ed the entire conf dir path to be sure), FS still passes along the
offer of G722 from the endpoint, presumably since it's operating in
bypass-media mode.

Is there a setting to limit the codecs despite having bypass media set?
Could we work around this by getting rid of the global bypass media setting
and then setting bypass-media before bridging the call?

Thanks,
