Could anyone help me set up Asterisk in such a way that it makes SIP-SIP transfers using the REFER / NOTIFY method according to RFC-3515 ?
SCANARIO: - Asterisk registers with PSTN<->SIP VoIP provider "V" (Vonage) as a friend - Asterisk is located in Europe, Vonage in located US. - Asterisk acts as an autoattendant located in Europe. - Asterisk answers and incoming call from "V" - The caller browses the autoattendant and as a result is transferred to another number in US PSTN (also via "V") - The autoattendant on Asterisk hangs up. When this scenario is attempted in Europe on the excellent X-Pro Softphone (http://www.xten.net), the SIP-SIP transfer happens without any problems. However when the same transfer is attempted by Asterisk in the dialplan by the following command: exten => 800,1,Dial(SIP/Vonage_out/18005551212) ...the transfer does not work :( Since the transfer done by X-Pro SoftPhone works so nicely. I am enclosing its debug output below. I am not enclosing the Asterisk output because it is so convoluted, I doubt anyone could make anything out of it (can oblige though). Anyway the important difference is that X-Pro Softphone issues a REFER command to "V" but Asterisk does NOT !!! How can I make Asterisk do the SIP-SIP transfer with the REFER / NOTIFY methods according to RFC-3515 ? Below is X-Pro Softphone's debug output of a successful transfer according to RFC-3515 : -------------------------------------------------------- SEND TIME: 26251796 SEND >>
