Hi Everybody, I'm trying to make my asterisk dial a international call from a SER request of it. My ambient is like this. [Clients]--[SER]--[Asterisk]--[Go2Call] Client: My SIP clients. SER: My REGISTRAR/Proxy Server Asterisk: All other services(Voicemail,musiconhold etc) and also acting as an UAC dialing International Calls, because SER doesn't do that sending username, password and host. Go2Call: My International Sip Provider. For my Client Local Calls, its simple, its working fine, also for inbound calls. But if anyone of my clients want to dial an international Number, they must authenticate at ANOTHER server (Go2Call) to take an international line, to do so ... that's what I would like to do, configure SER, to make international calls based on first authenticating at Go2Call and then close the VoIP Tunnel. I'm very confused about that ... I've tried to configure the following line at sip.conf, obviously changing the username and the other needed date. exten => 6789,1,Dial(SIP/user:password@${EXTEN:2}@international_provider,30,rT) and nothing happens. SER is forwarding the requests normally, as I only see asterisk's log appear (asterisk -r , sip debug), when I press 2, which was the key I choose to forward the request to Asterisk. I don't know whatelse to do. I'm sure I'm missing some configuration. Can anybody help me ? Thanks in Advance. -- Felipe Martins Linux System Administrator Tep Solution Provider Mundivox Communications Rua Lauro Muller, 116/Sala 505 RJ - Brasil - 22290-906 Tel.: 55 21 3820-8839 Fax.: 55 21 3820-8844
