Hi, I'm one of the people behind VOP, your comment "Voice Operator Panel (VOP), and it's nice use of SIP REFER" raised my recent google alert and I figured I could help :) A REFER is used to ask a phone to initiate an INVITE/Replaces to another phone. The Refer-To field is used to tell the phone what is the contact of the other phone where to send the INVITE/Replaces. In your case the Refer-To contains "mailto:2...@alsterph.lan" as the remote contact. My guess is that the router can not resolve this SIP URI (its host) and then is unable to know where to send the INVITE/Replaces. In our software we have an option to use the remote URI instead of the remote contact in the Refer-To field to avoid/solve this problem. (but it breaks the REFER RFC3515) You can check if your phone has this kind of option, or you can modify your cisco DNS server to be able to resolve this host(alsterph.lan) or you can change your internal phones contacts to IPs instead of hosts. Hope it helps !
