Hi, i already post it in freeswitch-users but nobody reply, now try there. I have questions about fs and not sip protocols, call scheme like this - user1-sip->fs-sip->user2, as i see if in sip profile enable inbound-proxy-media SDP is goes end-to-end if sip is on both call legs, if call goes throuch another protocol module, for example my mod_h323 (call scheme like user1-sip->fs-h323->someH323Ep) there is no way to negotiate codec because i have no SDP from called party for example and have no way to insert it on sip leg, or i don't see this way? This issue slow down my development, especially t38 part becouse i don't known how to resolve this in true way. C уважением With Best Regards Георгиевский Юрий.
