Here's the good news. Sine there are very few (aka none) implementations of RFC 4474 in the field now, we might be able to argue that by providing a way to properly handle PSTN numbers at gateways BEFORE we get deployment lets us work around the problem. As for numeric user IDs, there's no technical reason that "sip:[EMAIL PROTECTED] ;" can't REGISTER and authenticate as the authorized user at "example.com". So, pure IP endpoints can authenticate using Identity. It;s the behavior of the PSTN gateways that induces the problem. -- dean _______________________________________________ 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
