Hi all,

We have Exchange 2010 standard as part of our subscription Action pack and i'm looking to install it on our server to make use of the various unified messaging functionality, particularly voice mail.
I'm going to set it up for our new office which sits around 10 to 15 staff but usually only about 3 in there at any one time

I can install and configure Exchange to do what i want it to do, but its the hardware side of things i'm not too sure about.

Can you give me advice on the (UK) requirements, as i really don't know where to start.

My rough idea of the solution is as follows:

We use a voip gateway to terminate the incoming phone lines

then.. connect the voip gateway to the server?

I hope you can help me on this issue, i would greatly appreciate anything you can offer.

Here are a couple good guides:


If your existing pbx supports sip you should be able to connect directly to the pbx shown in the guide above. If you are trying to do this all without a pbx as it sorta sounds like you are from the "terminiating stuff at the voip gateway" statement you would need some from of pbx to handle call related functions, or deploy OCS which is microsoft's offering in that space.

By design the UM role in Exchange only handles voicemail, you will need something else to handle the "phone" functions.

Depends on your PBX. Some pointers to get you going:
Telephony Advisor (compatible hardware) Connecting UM to PBX Info on PBX/IP-PBX

Here a more practical hands-on with Trixbox:

When you think you're done you can test your setup using the UM Test Phone (or use your own softphone app)

(Note this is for Exchange 2007/2010 RTM, for 2010 SP1 (Beta) use the new UM Troubleshooting Tool
