Darren,

You should use the same dial plan. I have no way to test this, but believe it will work.

Can ocsumutil be done on the command line?? I would like to automate the creation of these when I create my Auto Attendants via power shell.

Thanks,
Andrew

Hi Drago,
I have an existing Exchange 2010 SP1 deployment with UM working along side our Cisco call managers for about 2 years. We are just deploying Lync 2010 and would like to integrate this with UM as well. Do I have to create a new dial plan in Exchange or can Lync use the existing dial plan ?

Any Advise,

Darren.

I've set up the UM with Lync with no problems, except nobody can call direct to extensions.

When you ring the switchboard, the recorded message starts 'Welcome to ABC..'. I try and dial the extension but nothing happens. Then it goes to the Response Groups within Lync, for press 1 for this, press 2 for that, etc. Any extension dialing here is going to go through to a group.

I've set up all the UM dial plans and auto attendants and I can't work out why this isn't working

Thanks

Paul

And what if I try to add certificate on UM and I got an error:
The certificate status could not be determined because the revocation check failed.
??
Tried to manage it in many ways, but no good result till now.
Any ideas ?

I used that cmdlet because for some odd reason the OcsUmUtil.exe says it couldn't find a domain controller in my domain. It can find the dial plan and i know there is nothing wrong with the DC as if there was everything in the domain would break. I never realised that cmdlet was only for the hosted setup though?

Shawn, New-CsExUmContact apparently is used to “Creates a new Auto Attendant or Subscriber Access contact object for hosted Exchange Unified Messaging (UM)” as per this article: http://technet.microsoft.com/en-us/library/gg398139.aspx Note the word “hosted”.

I would delete the two objects and use “OcsUmUtil.exe” as described above and see what happens…

Thanks for the prompt reply.
I used the above cmdlet to create both the SA and the AA. My set up is very simple. One multi role Exchange 2010 server and One Lync server.

2011-10-12T12:59:18.556-04:00

Incomplete hosted voicemail configuration
HostedVoicemailPolicy is not completely configured for [SA@domain.internal].
Cause: Destination or Organization setting might not have proper value.
Resolution:
Ensure that both Destination as well as Organization settings have valid values.

I get the above error when trying to dial the Subscriber or the Auto Attendant. For the life of me i cannot figure it out. There is no problem with users making calls to voice mail or to each other from the Lync client. Its only the numbers for both the SA and AA that fail any ideas?

2011-05-18T05:33:15.854-04:00

I just confirmed (with OCS R2 and Exchg 2007 --> 2010 UM migration) if the 2010 SP1 UM server does not have the UM server FQDN in the CN of the UM certificate, calls from OCS to 2010 UM will be unsuccessful.

2011-05-17T14:43:28.851-04:00

If you co-locate UM role with consolidated Exchange Server, your question is self-explanatory (smile), since we would have CN=FQDN and SAN=mail, autodiscover etc.
For standalone, I think SAN should do, because after all, UM and Lync do TLS and not MTLS, where the CN must match the machine FQDN.
However, I have not tested this scenario. Let us know what result you get, if you do...

Hi Drago,

for 2010 SP1 UM, is that a requirement: UM-assigned certificate CommonName (CN) attribute has to match the FQDN of the UM server or is it enought to have the UM server FQDN somewhere in the SAN list?

Can you verify your domain Root certificate is present in Trusted Root Certificate Authority store on the UM server?

Also, by default, the UM server uses self signed certificate. Did you assign the new certificate to the UM role as described above?

Hey Drago,

I have assigned certificate to the UM service
Get-ExchangeCertificate
[PS] C:\Windows\system32>Enable-ExchangeCertificate -Services UM -Thumbprint C39006265E9274FF9BDE790AEE02AABAC9388A79

Restarted UM service

Now I am able to start UM service, but when I dial Voice mail number I am getting below error under event logs.

Thanks for your help.

The Unified Messaging server failed to exchange the required certificates with an IP gateway to enable Transport Layer Security (TLS) for an incoming call. Please check that this is a configured TLS peer and that the certificates being used are correct. More information: A TLS failure occurred because the certificate presented by the remote server wasn't trusted. The error code = 0x800B0109 and the message = A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider..

Thanks for catching this Real,

Indeed, I forgot to include the step for requesting and assigning certificate to UM server. Since we will use TLS, certificate must be present or the service will not start. Will update the post later today.
