Hi gentleman I've configured SER to forward every call starting with sip uri request "1" to Asterisk. I need to configure Asterisk as a Sip UAC in order to make it call to my other SIP Provider outside my network, sending username and password for authentication. I've read at www.voip-info.org some articles but found none that could suit to my needs, but yet I've found an article which explains an implementation very similiar to what I need (http://www.voip-info.org/wiki-Asterisk+voicepulse+connect), but in my solution, I don't use IAX just sip terminatino via Internet. I've tried to do exactly as this tutorial said, but with one difference, all the entries at iax.conf I've made at sip.conf. The result is that I can still connect my sip phone to my server but it doesn't give me an outside line after I press 1. Have anyone implemented this solution or know what I may be doing wrong ?? My configurations are following below: Extensions.conf exten => 1,1,Dial(SIP/<username>:<password>@go2call,30,rT) exten => 2,1,Playback(tt-weasels) exten => 2,2,Hangup() exten => 3,1,Playback(tt-weasels) Sip.conf [go2call] context = go2call username=<username> secret=<password> auth=md5 type=friend host=<go2callhost> -- Felipe Martins TEP Solution & New Technologies Mundivox Communications fmartins@mundivox.com Site: www.mundivox.com Tel.: +55 +21 +3820 8839 Cel.: +55 +21 +9823 8602 Fax.: +55 +21 +3820 8844
