It supposed that when your proxy receives an incoming call from a PSTN gateway it will perform a lookup against the location server, so the RURI will be changed with the local user associated to that E164 number, so the INVITE after the lookup would be: INVITE sip:[EMAIL PROTECTED] SIP/2.0 Via: SIP/2.0/UDP PROXY:5060;branch=z9hG4bK-newbranch Via: SIP/2.0/UDP useragent.acmerockets.com:5060;branch=z9hG4bK-a111 From: "John Doe" <sip:[EMAIL PROTECTED];user=phone>;tag=9802748 To: <sip:[EMAIL PROTECTED];user=phone> Call-ID: 245780247857024504 CSeq: 1 INVITE Max-Forwards: 69 > Doubt - 2 : Will any sip phone allow us to dial a number starting with "+" > ( Eg +17705551211 ) "+" is a perfectly valid character in a URI username. Some desktop phones don't allow writting "+", this is why they use "00" and the proxy would translate it to "+" (if needed). Some phones allow writing "+" by pressing "#" for a while. And if you use a softphone of course you can use "+". -- Iñaki Baz Castillo <[EMAIL PROTECTED]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
