Hello, As with my previous update, I'm using the skeleton configurations (with minor changes, such as defining an external voicemail destination) just for testing purposes. With the skeleton configurations, I'm still seeing that the INVITE packet to the voicemail server sent first, and then the CANCEL to the second endpoint (please see SIP trace below). In this call example the second endpoint is a PBX, and is configured to route unanswered calls towards it's own local voicemail system. Is there a way to switch the behaviour so that the CANCEL packet towards endpoint 2 is sent FIRST; and then the INVITE to the voicemail system second? Thank you.
