If the proxy must see all requests within the dialog, the proxy must insert a Record-Route header into the dialog-forming request as it passes through. > X-Lite Client's are configured with the Proxy Server IP address. However, > the BYE msg is never received at the Proxy. Many clients permit configuring an "outbound proxy". That is not part of the standard, but is a common feature of many products. Usually, it means that *all* requests by the client are sent to the outbound proxy, regardless of the standard SIP addressing rules. Some clients may interpret the outbound proxy to only receive dialog-forming requests. > I tried intercepting SIP messages via Wireshark, but it does work either.

It helps if you plug all the devices into a "hub", a device which is stupid enough that it relays all incoming Ethernet frames to *all* outgoing ports. Then if you run Wireshark on a computer connected to the hub and set Wireshark to capture in "promiscuous" mode (accepting all destination addresses), it will see the Ethernet frames between any two hosts on the hub.
