Oh, that sounds to be a lot of work... It seems that this is Pandora's box, Benny mentioned somewhen :) Wouldn't you agree, that this big amount of requirements could prevent IMS from leaving the labs and getting really successful? Or do I overinterpret this, and implementing the MUST HAVE could be done with a snip? BTW: Are you working on PJSIP's IMS capabilities?

The one that should be supported as well are : RFC3321 and RFC3322 for Signaling Compression RFC3323 about the Private Field for privacy RFC3325 (very important) Private Extensions to SIP for Asserted Identity within Trusted Networks RFC3329 Security between the UA and First hope RFC3455 Private Header (P-Header) Extensions to SIP for the 3GPP RFC3486 Compressing SIP (for SigComp) RFC3892 should be fully supported for Session Mobility RFC4083 is interesting as well, describing the requirement of SIP by the 3GPP That's it I think. I've based this list on this page http://www.tech-invite.com/Ti-sip-RFCs.html. If anything else comes to my mind, I'll complete the list. Regards, Olivier B.
