I have a question that's been knocking me down since last night. Typically I can troubleshoot anything but I'm feeling a serious mental block right now. I have 4 CIPC phones registered to CUCM, each acting as a seperate PSTN phone. CUCM has a H.323 gateway configured pointing to a PSTN 2811 router which has (4) 2MFT-T1 cards in it. Each card connects to a seperate 2811 on port 0/0/0 as a ISDN PRI connection.
The problem I'm having, and what I feel should work, isn't, is that because I have 4 CIPC phones registered to CUCM with each Line 5 as 911, CUCM obviously see's that as a shared line between the 4 phones.
When I place a call from a remote location, say Branch A it rings its perspective CIPC via the T1 PRI as expected. Same with Branch B, C, D. However, when I dial 911 from any Branch location, it rings all PSTN CIPC phones @ 911 because technically they are a shared line via CUCM.
I was thinking I'd write a translation rule (s) on the PSTN router that would match a call inbound from each Branch using its caller-id and forward those specific calls to their own dedicated voice port, ie 0/0/0:23 for Branch 1, 0/1/0:23 for Branch 2 on the PSTN router.
Has anyone configured a similar setup or have any suggestions on how to accomplish this? It may hit me after lunch but as of right now, my mind is a blur.

Awesome, thanks Chris. As soon as I read your post I had one of those "wait, what" moments. Meaning, I already had partitions/css's setup for my entire setup.. However, I set the hard disk on my PSTN CUCM to Non-persistant mode and it's been running for a quite sometime like that. But, the power recently went out and well, back to no-saved changes it went. Didn't even think to check that.
