Hi,<br>I have seen similar post several times on the list but without a proper solution. Is it possible to add custom SIP Headers in 1xx or 2xx response. The SIPAddHeader only works for initial INVITE. Is there any workaround for this. There are certain polycom phones which can open up an URL when a Access-URL SIP Header is sent to it in 200 ok. This can be very useful to make the user's experience interactive with such phones.<br>
Any help in achieving this is highly appreciated.<br><br>Thanks,<br><br>--- Jayesh
