Hi,<br>
<br>
I am using an architecture with Ser and Asterisk.<br>
<br>
When Ser forwards the calls to asterisk, everything is all right. the caller has a &quot;ringing&quot; message and the callee rings.<br>
<br>
when the callee picks up, the caller has a &quot;connecting&quot; message but the callee hungs up suddenly.<br>
<br>
my asterisk shows the message:&nbsp; -- Got SIP Response 503 &quot;server error&quot; back from Ser_ip --<br>
<br>
how can i tell to asterisk to setup the call ?<br>
<br>
thank you !<br clear="all"><br>-- <br>BASRAOUI Karim
