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

[Roland Hänel]

Hi,

All these solutions only work for the specific case that the re-INVITE is
done to match an outgoing call (bridge / transfer). What I'm looking for is
a way to initiate a re-negotiation, not necessarily because the call is
going to be bridged. For example to change the codec prior to entering a
conference.

Greetings,
Roland
