I have a Unified Messagning server, a communications server (for my office comminicator), an exchange 2010 server, and a mediation Server. So far my office communicator works well and we can chat and call each other through comminicator. NOw i want to take it to the next step and have the UM server. I want to get off of our current VIOP service and have things managed internally. I want to setup it up so i can test it internally like calling another user and leaving a voicemail. please help

Yes I have the intial part but Do i need to download a third party PBX to configuere VM to the exchange.

Commented:
Not if your users are already using communicator to make their phone calls...

Commented:
I want to integrate user to be able to receive calls from outside lines as well.

Commented:
How do you have your phone lines right now?  Are they just PSTN lines through a T1 provider?  Or do you currently have a SIP provider?

You can use regular phone lines provided by a T1 provider, but you will need a device such as a Dialogic Media Gateway to convert those signals into something that the OCS Mediation server can utilize.

The other option is to get a SIP provider that you would connect to via the Internet.  This would require some internet bandwidth though, so you need to plan for that accordingly.  Many SIP providers require you to get a separate internet connection through that provider if you want to do the SIP service.  I have worked with Global Crossing though and they generally do NOT require that and as long as your internet connection passes their QoS tests, they will let you use your own.

Here is a list of MS-approved providers:  http://technet.microsoft.com/en-us/office/ocs/bb735838.aspx

Right now I have no external phones setup. What is planned is to have one the of the approved MS providers provide us with a Sip trunk. My concern is to have the phone setup working internally and then when we plug in the sip trunk info into the mediation server.. the external features should work. Right now I have auto attendants created and I have SA working. Thought right now when i dail my auto attendant.. i get an error.

Commented:
What's the error?

Author

Commented:
Well i dial the AA i get
 An error occurred during the call. More details (ID:1)
i click on the details and nothing. I dont ever get the greeting or anything. But my SA works fine.

Commented:
have you check the office communications server event log for corresponding errors?

Author

Commented:
nothing relevent

Commented:
Just to clarify, you looked in the event viewer under the "Office Communications Server" log, right?  That's a separate log from the System, Application, and Security logs.

Author

Commented:
yes i did check that and nothing or relvance. I did run the OCSUMUTIL and i do get a message:
This dial plan has at least one auto-attendant that does not have a corresponding contact object in OCS.

Commented:
Does the following post help at all?  http://social.technet.microsoft.com/Forums/en-US/ocsucintegration/thread/bbc05ad1-6e15-4064-be75-654251c44960

Can you check Exchange Management Console to verify that you have a UM auto attendant configured and that a corresponding Exchange mailbox exists?

Author

Commented:
i have a Ad object.. but i can't find it's mailbox in 2010 exchange... but also dont see the SA mailbox either...

Commented:
did you run the OCSUMUTIL utility using an account that is a member of the RTCUniversalUserAdmins group as described in the following article?  http://technet.microsoft.com/en-us/library/bb803643(office.12).aspx

Author

Commented:
yes

Author

Commented:
yeah nothing there could really help me with my auto attendant. a new one following the inscructions but i still can't call the number internally.

Commented:
In the OCS console, do you see the auto attendant show up as an OCS-enabled user?  If so, is its type "auto attendant" and does it have something configured under Telephony->Line URI?

Author

Commented:
yes it is listed and in the Line URI it has the full number +1xxx-xxx-xxxx number in it (dash not included)

 Resolution:
 If this error continues to occur, please contact your network administrator. The network administrator can use a tool like winerror.exe from the Windows Resource Kit or lcserror.exe from the Office Communications Server Resource Kit in order to interpret any error codes listed above.
Commented:
Does the auto attendant have an extension configured as well?  You can do this via that "line URI" property:  ext=XXX, where XXX is a 3-digit extension.  Or do you not have extensions enabled right now?

It sounds like you may have some errors in your dial plan--have you double checked that your dial plan is correct?  I would go ahead and specify an extension for the auto attendant to make it easier to test its basic functionality.

Commented:
well i finally got it!!
the Line URI is a full 10 digit number and the there is a mediation server in play that takes over the handling of calls when it sees that. Tricky but it works now. this was a tough one but that you for your help!!!
