Diferent network region 2

[Montero84]

Hello,

Why is that I have some IP phone registered in region 1 and others registered in region 2? is that normal?

Thanks in advance!

Well, if you have the phones registering to 2 different C-LAN cards and those cards are in different network regions...that would explain it.

That is the weird thing.. because my phones are register directly to the processor...

What communication manager release?

What about ip-network-map. do you have something defined in there to manually assign certain IP ranges to certain network regions?

Yeah, I can see a range of IP there.. defined for region 2... is that necessary?.. I am not an expert about network regions... what is the idea of having the range of IP defined there?... thanks again!

I have CM 5.2

It's used for manually assigning IP ranges to different network regions. For example, office A has a known ip range of 192.1.1.100 to 199. You want office A to be in region 1 for example. Office B has IP range 192.1.1.200 to 299. Office B is remotely located and you want to control calls/bandwidth to that site and force it to use G.729 codec between office A and office B. This is a reason why you might want to use ip-network-map to force phones using certain IPs into a certain network region. I don't use network mapping at the moment since we have mostly digital phones and the digital phones assume the network region of the cabinet they're physically connected to so that works for us. If we start using a lot of IP phones though, we may need to start using the ip network map function. Also, if you register an IP phone to a CLAN card, the IP phone assumes the net region that's assigned to that CLAN card so no network map is needed for that. If you're registering the phone to a single server somewhere and these phones are in several different physical locations (different cities for example), then network mapping may make sense to use.

Thanks so much!

J1121... sorry to bother.. one last question.. In my case.. I have about 400 Ip phones... I have two ranges of IPs and two VLANs. everything is working fine. The group of phones in VLAN A are using network region 2 and the group in VLAN B are using network region 1. since the phones are in same campus, would you agree I don't really need the network-map?

Thanks again!

Hmmm....just thinking about it real quick, I guess I don't see a reason why you couldn't just put all of your resources into the same network region (C-LAN cards, Medpro, VAL card, etc)...and do away with the network map. However, if you have access to whoever configured this originally, I'd ask them why it was done. They may have had a reason for doing this that I can't think of at the moment.

my 2 cents about network region and ip phones.

a. fist check what it is defined on the dhcp scope of the phones. it will show to which clan they register and therefore network region

b. use ip-network-map to assign network regions to ip ranges as mentioned on the thread.

c. check/uncheck the option "Allow H.323 Endpoints?" as necessary for a clan.

d. use virtual or ghost network regions to separate handsets. Example: let's say you have location A and B with IP Phones on both. If for any reason clan blockage/network/power/etc reason your gateway in location B becomes unavailable the IP Phones on it could register to location A automatically and you end up with all phones registered in once place with the network/bandwidth/codec implications it has.
