At one of the recent IETF's, there was a session on SIP interop issues. One of the issues we've found is different expectations about SIP header length and body size support. We have found some implementations sending rather large bodies, where "rather large" is greater than 1MB. Ignoring the reasons some middleboxes have policies to block such large bodies, the reason they have such policies is because lots of devices simply can't handle them. There are other issues with it too, such as head-of-line blocking and inability to send it on over UDP.
So my question is, is it appropriate for a draft such as draft-ietf-sip-body-handling-01.txt to potentially define a maximum, or at least guidance about it? It doesn't have to say one cannot send something larger - just say that receivers should only be expected to accept up to X byte large bodies. I know this is an unpleasant topic, but it's causing interop issues which are causing certain SIP uses to fail in the real world. -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
