Customer's main site has CCM 4.2(3) with a 2811 setup as an H323 gateway. The 2811 has an NM-HD-2V with 2 VIC2-4FXO cards to handle the 8 lines to the telco. It also has PVDM2-16 and PVDM2-32 modules.
The remote site has a 2650XM setup as an H323 gateway. The 2650XM has an NM-2V with 2 VIC-2FXO cards to handle 3 lines to the telco and 1 line to an overhead paging system.
The 2 locations are within the same local calling area and the customer would like to move the 3 CO lines from the remote site and put them in the 2811 at the main site. So, I would need to have 11 FXO ports on the 2811 with the option of 12 FXO ports for adding another line to the telco. My first question is what modules/cards do I need to handle 12 FXO ports on a 2811 since I would probably need to take out the NM-HD-2V since it only has 2 slots, right?
My second question is regarding the call routing. Incoming calls are simply PLAR'd to a CTI Route point to play a Unity call handler, so I think I'm OK there. But, the outbound calls at the remote site still need to go out to the PSTN using the 3 FXO ports connected to their CO lines at the main site. Each site currently has a 9.@ route pattern in each site's partition so calls go out the correct gateway. I would have to make the phones at the remote site use the 9.@ that uses the main site 2811 gateway, but how would I tell the 2811 to use the 3 FXO ports that are connected to the remote site's lines?
One issue I see with this is 911 and letting emergency services know that the is at the remote site, not the main site. What options do I have?
Just to note - the main site has about 40 phones. The remote site has about 8 phones.
