				Hi,
 We have a MXe running ICP 3000 version 9. I want to set up direct SIP integration with a Exchange 2010 SP1 Unified Messaging server. IS this possible for this particular version?
 
 Also, how much bandwidth does a single call being sent over an IP trunk between two Mitel PABX's take up?

				I would greatly suggest upgrading to MCD as there is a lot of changes to SIP. It depends on call compression but roughly 80k.
