Hello,<br><br>I am using SER as a redirect server.<br>I recently posted almost the same question.<br>This time the format of the CONTACT is different. It contains call information.<br><br>Recently I came across an issue where the 302 sent back by SER is
<br>not liked by a soft switch. Particularly , the format of the CONTACT <br>field according to the softswitch..
<br><br>Here is an excerpt of the 302 reply send back ...<br><span><font color="#0000ff" face="Tahoma" size="2"><br>Session Initiation Protocol<br>&nbsp;&nbsp;&nbsp; Status-Line: SIP/2.0 302 MovedTemporarily<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Status-Code: 302
