MWI Problems

Here is the scenario:

MWI lamps are never lit on IP phones. I can dial the MWIs to turn the lamps on manually. If I put a phone in the same CSS as the VM ports and MWIs, I can call the IP phones. Status Monitor shows Dialing MWI 'dn' repeatedly. The application log show

Re: MWI Problems

You didn't mention how you have the partition setup. You might check to see if the MWI DN's partition is setup the same as the phones. I'm not sure if this is required (its how I have mine setup) but you could do a test to see. Also in Unity be sure on the subscriber>>>Messages>>>MWI, that USE MWI for messages notification is checked. And just below that under the field MWI Extension that extension reads X.

Good luck.

Re: MWI Problems

I have the MWI DNs in the SystemPart. The phones are in a different partition. This has worked in the past as long as the partitions can call each other. The Unity subscriber is set to notify via MWI and I have verified (3 times) that the CCM and Unity on/off numbers match.

Thanks.

Re: MWI Problems

I forgot to mention in the previous post to check CCM and Unity to be sure you have the MWI DN's setup the same. For example: DN1 = MWI ON and DN2 = MWI OFF. We got ours backwards during an upgrade once and the MWI's quite working.
