This is about whether the first reliable provisional response must contain an SDP offer.

It should have been avoided to put too many jobs into PRACK, I miss KISS(Keep It Simple and Stupid) principle Regards, -Rockson ________________________________ From: sipping-bounces@xxxxxxxx [mailto:sipping-bounces@xxxxxxxx] On Behalf Of Hadriel Kaplan Sent: Tuesday, March 31, 2009 9:50 PM To: Christer Holmberg; sipping@xxxxxxxx Subject: Re: PRACK: Change MUST requirement to include SDP offer in first reliable provisional response In hindsight I'm thinking we probably also shouldn't have made the SDP answer (or another offer) required or even possible in the PRACK either. I think it should have been for one and only one purpose: to acknowledge receipt of the provisional response. -hadriel _______________________________________________ Sipping mailing list https://www.ietf.org/mailman/listinfo/sipping This list is for NEW development of the application of SIP Use sip-implementors@xxxxxxxxxxxxxxx for questions on current sip Use sip@xxxxxxxx for new developments of core SIP
