Vocera should respect the proposed SIP PORT instead of communicating to source port (required for Mitel Nupoint voicemail support)
When calling a Mitel Deskphone from a badge, if the user is directed to the voicemail, there is no possibility to let a voicemail though the badge user is presented with the option.
After the tone to leave a message, the call is cut short and the users are presented with the "after voice mail" menu (press 7 to validate, etc.)
Packet capture shows that the VSTG change the SIP destination port during the call. It uses the correct destination port from the SIP invite for the first 14 packets and then switch to a new port - the one from the Mitel RTP src.
Mitel Nupoint voicemail uses asynchronous ports. A different port to listen to the media and to answer.
