Network Regions PE and CLAN

[cef2lion]

New to our environment. Hope I get the terms correct. We are one location but a few buildings use Gateways via fiber.

I have been looking at how our network regions are setup. We have CM(PE/PROCR), G650, 2 G430, 1 G700. None of the gateways have trunks. All Gateways have just analog and Digital media modules.

We are using all H323 IP phones. No SIP.

We have 4 regions defined. Our IP map has three regions but the DHCP IP pool space only maps to region 1. Region 2 and 3 IP space I think were planned for future use. All regions will use the same IP space.

All our CLAN cards are in region 1 except one is in region 2. Based on our IP mapping I don't see how that CLAN card in region 2 would ever get used.

Our PE or PROCR is in region 200. Wondering why it was put in a region by itself it appears.

The IP phones all register to the CLAN cards as the CLAN cards are in region 1 and the IP mapping is region 1.

To get the IP phones to register to the PE I assume I need to change the PE from region 200 to region 1 and have adjust the priority lower then the CLAN cards. What would be the impact of moving PE to region 1? I'm not sure why its in region 200 to begin with.

I've seen procr placed into a region with no media resources (typically an intervening/ghost region) when the system has multiple SIP trunks to the same Session Mgr for different types of traffic. Since the near-end node on the signaling groups is usually procr, placing procr into a region with no resources forces CM to select DSP based on the far-end network region defined on the signaling group rather than always using DSP from procr's region.

As long as region 200 has connections defined to all regions with phones/trunks, you can keep procr there and direct the phones to register with procr's IP. Use the ip-network-map table to statically assign voice subnets to the appropriate region for their location or local media gateway. An endpoint can use procr as a registrar but be a member of a network region that is different than procr.

Thank you for the response and the suggestion to leave procr in region 200 and change the ip-network-map table.

Is there a way to view/verify that our region 200 with procr has connections defined to all regions with phones/trunks?

I know how to change the ip-network-map table entry from its current region of 1 to 200. As suggested the endpoints should then register with procr. If I make this change is it service effecting to the endpoints at the time of the change? Or do they continue to be registered to the CLAN card they are registered until they reboot?

disp ip-network-r x

This will show all connections for region x and what codec set is enforced. Pretty sure changing the network map table to force an endpoint into a different region is a hot change, but consider doing it afterhours to be safe.
