But sending it to the PSTN is a model for Internet communications?? Look, for better or worse, we have allowed proxies to recurse on 3xx. If you set a TEL uri in the contact, the upstream proxy can decide whether to recurse on that or not. If it chooses not to, it can pass the 3xx upstream, and the *next* proxy upstream can make the same decision, and so on. Now replace "tel:" with "sip:", and add the domain of the upstream proxy, and a user=phone. It may be ugly. It may be wrong. But it's working. And it's working across domains. And it's probably working better than tel would right now, imho. So where do we go from here? Option 1) Ignore it. This may only be a minor population of the sip community; or they may fix it themselves someday; or it may not be a real problem if they keep doing what they're doing. Option 2) Figure out how to make tel more successful. Option 3) Figure out how to make sip with user=phone a true alias. Option 4) ?? -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
