Some PSTN carriers reject calls when unsupported on PSTN side codec is set as primary. So sending G722 as a primary is a big deal... I wish to have "filter codecs out" ability on bypass media. On Thursday 11 July 2013 13:51:23 Ken Rice wrote:

As far as WAN bandwidth its the same as G722...

I¹m 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. We¹d rather ensure that G711 is used instead. Despite the fact that G722 is not enabled for any of the codec prefs (I grep¹ed the entire conf dir path to be sure), FS still passes along the offer of G722 from the endpoint, presumably since it¹s 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?
