Doghart, This is a tough one. I went through this a few months back. There are 2 ways to do this. My VAR tried to get me to pay for a trunk on both ends as this was the "easier" way to do it and recommended not doing the sip route as it was "hard". I was able to use SIP between our shoretel and cisco locations using SIP over MPLS with no issues. I currently do not have access to those systems or my documentation but, will late next week. PM me and I can send you some more info and some screen shots on how the SIP trunks were set up on each side. You will need SIP trunking licenses on the Shoretel side. Think about how many simultaneous calls you think they will connect. This will be the amount of licenses you will need. I would consider padding it with a few extra to be safe.

Thanks,

-Mike
