[Freeswitch-users] Trigger re-INVITE with different SDP during a call

[Zohair Raza]

Hi,

Try setting bypass_media_after_bridge=true

with <param name="inbound-codec-negotiation" value="greedy"/> in sofia
profile and then pass absolute_codec_string
before bridge on the new leg like

<action application="export"
data="nolocal:absolute_codec_string=PCMA,PCMU"/>

bypass_media_after_bridge=true is a bit similar to canreinvite of asterisk

Regards,
Zohair Raza
