MWI quit working HELP

[pjt8537]

Running Unity 4.0(4)SR1 in a dual integration environment. Recently added 1200 users to the system and now MWI is not working on the PBX side. The Call Manager side works fine. We are running a dual PBX Link 48 port serial integration (one setup for calls & MWI the other for calls only) on the PBX side. It was all working fine and just quit working. We have tried rebooting the PBX links with no luck. Also, from the Integration monitor screen in Unity the MWI signals seem to be generated. Is there a way to monitor MWI on the PBX link box to make sure they are getting to the PBX? We can dial the Leave Word Calling Activation and Deactivation codes on other phones, so that is working. It almost seems as if the volume is maiking it unbelievably slow.Also, is there a preferred setup for the 4.0(4) SR1 Unity version. We are on an Avaya G3R V11. Any ideas or help would be greatly appreciated.

We have an Avaya Communication Manager 2.1. Cisco has actually recommended to NOT use the serial integration. It should be a true analog - where MWI is sent through the analog ports, not the PBXLink box. Still, MWI is not working properly. Apparently, the MWI Off Message MUST be sent through the same port as the MWI On message for the related message. Causing all sorts of issues with us.

Are any MWI requests working? on or off?

One thing to try is to take the digital line from PBXLink PortA (the one that does MWI) and connect it to a real 8434 or 7434 phone. Then try setting and clearing LWC from there. That will rule out the possiblitity that the PBX is somehow restricting that line.

If that's not it then we need to dig a bit deeper. You have two PBXLink boxes daisy-chained together? The one directly connected to Unity MUST be the one configured for MWI. Also, PortA of that box should be doing the MWI. It is highly recommended that PortA of that first PBXLink be dedicated for MWI traffic (i.e. don't use that digital line for any of the bridged line appearences).

Finally, are there any errors or warnings that show up on the MWI PBXLink? I believe you can check this through a menu option on the front panal, something like "Last Error".

Thanks Eric..... I did plug in a physical 8434 set into the line. The apparent problem was a software upgrade that occured on the PBX. It set the digital line ports in a download to station pending status. Until a physical phone set was plugged in letting the new translations download, it hung the LWC activation ability. Something to put in the memory for next time. Thanks again for the response!
