Dear sirs: I almost have implemented the PSTN termination service in my Sip Proxy using a third-party Gateway provider in Miami, but im having some trouble translating the phone numbers in my sip Proxy to GW numbers that the provider gave me for each user of my system that wanted to have a PSTN Termination Service. I was talking to the GW people and they told me that they don't know if the Remote-Party-ID header field is supported by them. I've been testing registering to my SIP Proxy with a GW number (provided by the GW people) as username ("sip:gateway#@mydomain.com") and succesfully called to anywhere i wanted. But the real issue comes when i register with a username of my domain ("sip:username@mydomain.com") the GW send me to an IVR and ask me for a pin number. I´m sending the Remote-Party-ID with append_rpid_hf(); Also, the GW people told me that they check the From field of the SIP Header for the GW numbers they gave me. If i´m interested in leave alone my clients numeration (which i am!!) i should have to rewrite the From Header Field which will cause interop problems. Guys i need some help, i´m lost, so close and so far at the same time. Is there a way to translate the numbers of my domain to the numbers of the gw provider?
