Hi Guys Does anyone know of a way I can change the contact field in the sip invite to display sip:username:ip instead of sip:did:ip We need to do this without changing the from field. I tried using fromuser=username but that just modifies both the contact and the from parameter I know in freeswitch they use the parameter extension-In-Contact Has anyone managed to do this before? -------------- next part -------------- An HTML attachment was scrubbed...
