VPIM MWI issue

Unanswered Question
Jul 27th, 2008


I am configuring VPIM between Unity and CUE in different domains. The Exchange Server is installed together with Unity and is being used as the DNS server. The Messages and the MWI's for messages from Unity to CUE are working fine. However the messages from CUE get delivered to the Unity site but the MWI does not work and nor is the caller able to retrieve the messages when he logs on to Unity. There are no remote mailboxes for the users.

I can see that the Subject line of the messages that reach the Exchange Server is blank. I have been told that it should indicate the message being a VPIM message of some sort.

Please feel free to ask for more specific information to help trouble shoot. I don't know what configuration parameters to post here.

Thank you in advance for any help.

I have this problem too.

are you saying that the messages do not get delivered to Unity...

I believe you will need to configure remote users as this is where you will associate the location id with the user, so cue can know how to route vpim messages

Thanks. I would say that the messages are getting delivered to Exchange Mailbox but Unity is not able to recognise them. I may be wrong. I believe the problem could be that the Subject line of the messages delivered to the mailbox at the Exchange server is blank.

How do you know the message is getting delivered? Try and use message tracke on exchange to know whats happening to the message.

Also can you check on your smtp domain name in your location configuration on CUE, that unity has this format..


So if the FQDN for oyur unity server is unity.ccie.com, then your smtp domain name should not be unity.ccie.com but ccie.com

I am quite sure that the messages are being delivered as I can see them usin the Outlook Web Access. http:///exchange and the usernaame and password of the user I want to check.

As you suggested I have checked the FQDN and the Domain configurations.

Another thing I want to say is I have changed the version of CME from 2.1.2 to 2.3.2 to rule out any software errors.

Have you done these two things

1. extend the ADschema for VPIM on unity

2. Install exchange voice connector

ShailendraK Sun, 07/27/2008 - 08:47

Yes both. Made sure that the version of Connector is ok.

When I was going through the documents there was some mention of some other update according to some Microsoft KB article. I am looking all over but cannot find it now. Would you know about it(if relevant).

Ayodeji oladipo... Sun, 07/27/2008 - 08:49

The only time you need the microsoft script update is when after installing voice connector, your version of this file woshm.ocx in wint/system32 folder is earlier than 5.6

Thank you for all your help aokanlawon.

It is working now except the MWI. That could be a CSS and partition issue. The problem was VPIM transport event sink. The messages have the appropriate Subject line and the sender name. Will post if the MWI issue is not resolved.

Thanks again.

Let me know if the MWI comes on.

Can you dial the mwi number on the ip phone?

I actually dint know the mwi comes on for VPIM.

I was actually working on this integration on saturday! Can you post your CUE and Unity config as a word attachment here.

I can assure you that MWI works for VPIM. It is working for me now.

PM me for congif.

ShailendraK Sun, 07/27/2008 - 10:51

I think there is no PM option on the forum. Never thought of that.

There is nothing special to make MWI work. If the MWI is working with your within Site messages and the VPIM Transport Event Sink is doing its job, the MWI should work. I uninstalled and reinstalled VPIM Transport Event Sink and things started to work. Just two attachments to show the difference it made to the messages to the email

I will post my configs here and send an emai to you as well. Give me little bit of time.
