I have a UCM 7.1.3 environment with 7 h.323 gateways are each remote site - the gateways codec and dial peers are all standardized. We have a UNITY EXPRESS system installed into a 2800 router which is working fine except....
when inbound PSTN calls are forwarded on from the phone after going unanswered to the voicemail pilot number it just rings out. On my phone i can see the pilot number being initiated but I don't get the voicemail prompt. It just rings out.
Like i say voicemail works fine for every situation except incoming PSTN calls that are forwarded to voicemail from this site.
i've manage to track down via a CUE trace the problem and can't make head or tail of it. Below is some text from 2 traces. The first trace is from the problem site and the second trace is from a site that works ok. The problem line has been highlighted.
Has anyone any ideas where to look? - many thanks

Hi I eventually traced it to a mis configuraiton with my gateway and CSS. Make sure your remote sites gateway partition CSS includes the partition you have configured for your unity express.
All of my gateways used site_phones as the partition except the site i was having problems with. The gateway partiton was the last thing I looked at and found that it was site_internal. On checking the site_internal CSS I found it didn't contain the partition for the unity express..
Bumping this because I just ran into this issue, and this post helped me out a lot... here's a quick & dirty solution, and an explanation of what I think is going on with CUE when integrated to a CUCM (imho).
My gateways (CUBE, MGCP, H.323) all have an inbound CSS called PSTN-INBOUND which helps me manage inbound calls, translate & route them properly. This CSS only has access to PSTN-INBOUND-P which has a bunch of translation patterns that either strip the full number to an extension number in INTERNAL-P or perform other routing manipulations. This setup works fine with Unity Connection, but this doesn't work well with CUE.
CUE port DNs, defined as CTI Ports in Device-Phone, need to be dialable from the gateway's calling search space (and the CTI RP's CSS as well). I originally put them in my INTERNAL-P partition, just like the CTI Route Points that are used for AA, pilot number, AVT, etc. Calls to the CTI Route Points from inside the system work just fine as the CTI Port numbers are dialable from the phones. However this is not the case for calls coming in a gateway.
I think CUE performs a redirect using CTI to the DN of the port it wants the caller to go to. Since inbound calls from my GWs are using the PSTN-INBOUND CSS, you get a busy tone because it can't figure out where to route the call. So I set up a translation pattern in PSTN-INBOUND-P that matches my CTI DN range (190X) and simply changes the CSS to INTERNAL. Voila, it works. Took me a long while to figure that one out... CUE is not often integrated with CUCM, so there isn't much support or shared experience available out there.
You won't have this issue with Unity Connection, because most if not all calls directed to it hit a Hunt Pilot which does not care which P/CSS you are in when the HL/LG routes the call. As long as you are in the proper CSS to hit the Hunt Pilot's partition, anything else behind that HP/HL/LG doesn't matter.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
