boolean Set which list of codecs is offered to the B-leg.

FreeSWITCH used to take the codecs from the inbound A-leg and offer them out to the B-leg mixed with the configured list of outbound codecs. With large lists of codecs this can exceed the MTU of the UDP message and cause call setup failures.

As of FS-8321 -Authenticate to see issue details the old behavior now requires the variable media_mix_inbound_outbound_codecs=true as the new default behavior is to offer the exact same codecs on the outbound B-leg that were offered on the inbound A-leg.


<action application="set" data="media_mix_inbound_outbound_codecs=true"/>
