<DIV>Hi, all,</DIV>
<DIV>I want to use asterisk SIP as a proxy, and two softphone (Ubiquity SIP Phone) as user agent, like below:</DIV>
<DIV> </DIV>
<DIV>Softphone1<-------------->Asterisk SIP<------------>Softphone2</DIV>
<DIV>(User Agent) (Proxy) (User Agent)</DIV>
<DIV>155.69.xx.xx 155.69.yy.yy 155.69.zz.zz </DIV>
<DIV> zhou mysipproxy.com Reltec</DIV>
<DIV> </DIV>
<DIV>If I use softphone1(zhou) to dial softphone2(Reltec) directly, not accroess Asterisk SIP (proxy), it can work. But when I use asterisk SIP as a proxy, then Softphone1(zhou) shows "Not Found", and it seems it can not find softphone2's address.</DIV>
<DIV> </DIV>
<DIV>It seems an easy problem, but it waste me about one week's time. The main content in my [sip.conf] file is:</DIV>
<DIV> ... </DIV>
<DIV> [general]</DIV>
<DIV> port=5060</DIV>
<DIV> bindaddr=0.0.0.0</DIV>

<DIV> </DIV>
<DIV>The main content in my [extensions.conf] is:</DIV>
<DIV> ...</DIV>
<DIV> [bogon-calls]</DIV>
<DIV> exten=>_.,1,Congestion</DIV>
<DIV> [from-sip]</DIV>
<DIV> exten => 1, 1, Dial(SIP/zhou,20)</DIV>
<DIV> exten => 1, 102, Hangup</DIV>
<DIV>
<DIV> exten => 2, 1, Dial(SIP/Raytec,20)</DIV>
<DIV> exten => 2, 102, Hangup</DIV> </DIV>
<DIV>The result in asterisk SIP is listed below:</DIV>

<DIV>It seems the extensions.conf has some problem, but I don't know how to write the correct dialplan. Any suggestions will be appreciated.</DIV></DIV>
<DIV>Thanks.</DIV>
