Siprec?

Is there any possible way to use Asterisk as a SIPREC session recording client (RFC 7245)?

Yes, you can record incomming or outgoing calls…

I use it , works fine. But if you are looking for large scale recording I would look at Orecx. Opensource recording for callcenters and stuf.

I need to use Asterisk as the SIPREC client, i.e. send the audio/info to another recorder such as Nice or Verint.

XML Metadata cannot be extracted from the SDP multipart body and chan_sip cannot mix multiple audio streams in a single SIP session, as requested in SIPREC draft. Also, it seems SIPREC is not considered in pjsip yet (asterisk 12).
