Hi,

I am trying to come up with a simplified SIPREC compliant client, which would playback an existing recorded file to a third party server. It is a requirement of SIP RFC that the INVITE message from the SIPREC client has SDP attributes such as a=sendonly, a=label and so on. Further Contact URI in the SIP header needs to be updated to include '+sip.src' feature tag, "siprec" option tag in the Require header etc.

I was wondering if this is achievable in freeswitch in it's current state? Or am I required to come up with my own mod, such as mod_oreka, to send the INVITE with the required headers?

At Sangoma we did the SIPREC modifications to mod_sofia (e.g even adding a new file particularly for siprec) for our SBC product.

I can say the modifications to be decently complaint (e.g supporting XML recording meta data and separate streams) are non-trivial (not just one tweak here and there)

But I guess it's possible (depending on who you're trying to interop with) that you could get away with doing less than that.
