<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:times new roman, new york, times, serif;font-size:12pt"><DIV>Hi All,</DIV>
<DIV>I had a requirement of appending a text in the VIA header while forwarding the request to the PSTN gateway.</DIV>
<DIV>For eg:</DIV>
<DIV>When the call is forwarded to a PSTN gateway from my Openser server, I needed the Via header to be as follows:</DIV>
<DIV>Via: SIP/2.0/UDP 192.168.2.125;branch=z9hG4bK7e7c.877b4352;x-route-tag="cid:1234"</DIV>
<DIV> </DIV>
<DIV>x-route-tag="cid:1234" is what I want to append to the Via header that is going out of my proxy.</DIV>
<DIV> </DIV>
<DIV>I do not want to disturb the first Via header that has come in from the UA, I only want to append the text in the Via header when the message goes out of Openser proxy.</DIV>
<DIV>Can someone please guide me on which module can help me in doing this or what would be the right approach.</DIV>
<DIV> </DIV>
<DIV>Thanks in advance,</DIV>
<DIV> </DIV>
