Thank you Ovidiu. I had assumed that the Custom-Headers parameters works only for the initial INVITE request. It works as expected. I have another concern here:<div>I dont want the "100 Trying" response going out to the call initiator because I know that "407" is will obviously come from the "Proxy Opensips". While using t_relay I could have done that using the flags inside the t_relay function. Is it possible to avoid the "100 Trying" somehow when relaying the call in B2B mode?</div>
<div>To be honest, I have a web application which initiates the call and expects a "407" response and then will send the INVITE again with digest credentials. When that application gets the "100 Trying" response, the application gets confused :)</div>
<div>Either I will have to tweak the application to just ignore the 100 response which is little difficult or else find a way to avoid sending 100 response from opensips. Please Help !!</div><div><br></div><div>Thanks in advance.</div>

Try adding your extra headers to the "cusotm_headers" parameter:<br>
