No, I very clearly said "don't shoot the messenger", but that that is what I see happening. Clearly you SHOULD use a tel URI, or the sip URI with the domain of your cell phone (if it has such). But the reality is people AREN'T doing that very often, afaict. I am in no way suggesting 3263 rules should not be followed, nor that tel uri's shouldn't be used.
Juha asked how he could write a *sip* URI in a 302 to redirect to a cell phone, and I answered what he could try. I don't know why this is shocking - are you not seeing that often as well? [maybe it's just me] Don't get me wrong - I see 302's aplenty which point to a different domain as well, but in many of those cases the domain they point to is also not authoritative for the E.164 (ie, they're to transit peers). [Although with regard to 3263, I'm not sure what part of setting the contact uri to your own domain doesn't follow that. The target of that domain is reached (your proxy/pbx/whatever), and it can't route it locally because it has no such global user, so based on local policy it may determine an alternative path, typically to the PSTN.] -hadriel > -----Original Message----- > From: Paul Kyzivat [mailto:[EMAIL PROTECTED] > Sent: Sunday, April 13, 2008 12:25 AM > To: Hadriel Kaplan > Cc: Juha Heinanen; Francois Audet; SIP IETF; Dan WING; Dean Willis > Subject: Re: [Sip] E.164 - who owns it > > So you are telling me that you SHOULD forward someone to your own domain > to reach a phone number even when you know that your domain would not be > willing to route the resulting request from the forwardee.
