Hi All, I had a requirement of appending a text in the VIA header while forwarding the request to the PSTN gateway. For eg: When the call is forwarded to a PSTN gateway from my Openser server, I needed the Via header to be as follows: Via: SIP/2.0/UDP 192.168.2.125;branch=z9hG4bK7e7c.877b4352;x-route-tag="cid:1234" x-route-tag="cid:1234" is what I want to append to the Via header that is going out of my proxy. 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. Can someone please guide me on which module can help me in doing this or what would be the right approach. Thanks in advance, -- Jayesh

Hi Jayesh,
take a look at the textops modules, there are functions present to add/ manipulate header fields. I don't understand why you need to append the same parameter "x-route-tag" two times.. Instead of modifiying the VIA perhaps its possible to just add some new header, e.g. X-Route-Tag, this should be easier.
