Yes. Some folks think >1MB is ok.

That section of 3261 is about messages - it says nothing about bodies. Some devices reject requests with bodies that exceed a length, where that length is less than the full 64k for the whole message. For example, one of my companies' products will reject a SIP message with an overall body bigger than 32KB by default. It's configurable, but I think we're compliant to reject such by default. -hadriel _______________________________________________ Sip mailing list https://www.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip
