IP phones not registering 2

[TykeUK]

Current set up... 1 x s8700 with 6 remote offices containing a G700 and an S8300 LSP. CM2.0

When the WAN goes down between the main site and the remote site the phones should register with the LSP. However this is not the case, they sit there discovering and try to find the c-lan's at the main site. I have to dial into the G700 on the remote site, and manually change the network region in the ip-network-map to 1, then back to it's correct region before they will register.

All the DHCP scope, tftp settings etc are all set up correctly.

Has anyone come accross this before?

Is there an entry on page 2 of the ip-network-region form? LSP Names in priority order, this shuld have procr in each one!

 

[TykeUK]

Yes - this is set correctly.
This seems to be something of a 1 off as Avaya are even struggling to come up with something.

Thanks

Hello,

By default (and with no option on changing it) all LSP's processor-ip-interface belong to IP-network-region 1.

This means that if your media gateway or your IP stations belong to other network regions (eg. Network-Region 2,3,4...) you should administer network-region interconnectivity (ip-network-region form page 3) Otherwise the ip-stations or the G700 will not be able to register with the LSP.
So if you ip-stations are in ip-network-region 2, this should be able to communicate with ip-network-r 1 (you specify this in page 3 of the ip-netrwork-region form) on the main controler.

This is the responce I had from Avaya when I had the exact same problem. If you do a "list trace ras ip-address xxx.xxx.xxx.xxx" on the LSP where xxx.xxx.xxx.xxx is the ip-address of an IP station and you see denial event 2040 then this is the case.

Thanks - I have made this change and will test out of hours.

Hi Petran,

Many thanks for your help. I added in IP network region one and had to set this to Direct WAN. It now works ok.

Thankyou

Before (I don't know about CM2.0) you had to put the LSP in the DHCP string for the phones.. This way they'll search through their known gatekeeper settings to find one that is alive..

Hi Petran,
We have problems with our S8700 2.21 and 2 Lsp CM2.1
Each time link go down, a very small number off 4620 register in lsp and when we send a reset system 4 on lsp when the link backup, it take a too long time to register all ip-phone on primary server.
Most of time we reset ip phones manually but most of them display Extension in use.

I checked the ip-network-region of LSP and it set to 1 , so my ip network region 1 is set to not be able to communicate to other (because i don't have medpro in this network , only for clan of CMS an Billing ).

I can move cms/billing in another network region but i prefer to ask you before if you thinks to have a small number of ip phone register in lsp even their networtk
region can't communicate with LSP ip-network-region.
Of courses , ip stations can ping LSP and vice versa

Thank you in advance an sorry for language, i'am french...
Regards
Michael

The ip-network-region of the procr interface on the LSP is default set to 1 and cannot be changed. So on the main system the Ip stations should be able to communicate to regin 1. If you have a clan in region 1 and you do not want the ip stations to register with it then you should move it to another region.

I hope this is helpfull..

Petran.

Thanks Petran for you quick answer.
I did a change ip-interface procr on lsp and it appears i can change its network-regions, do you thinks is due to the version of Communication Manager (2.2 or 2.1) ?
I don't understand how small number of ip-phones can register in LSP and have bearer if they are not in the same ip-network reg ? have you an idea ?

Regards

 

[petran]

You can change that field but you cannot save translations on the lsp so after a reset the change will be lost...

In the main system all ip-network-regions that have ip-stations should be able to communicate with ip-network-region 1. In page 3 of the ip-network-regions form you can administer inter-region connectivity. So all regions with ip-stations should have a codec administered for connectivity with region 1.

Many many thanks Petran.

An idea : regarding I don't understand how small number of ip-phones can register in LSP and have bearer if they are not in the same ip-network reg ? have you an idea ?

[petran]

What do you mean by "small number of ip-phones can register in LSP and have bearer if they are not in the same ip-network reg ?"

Please give more details...

Hi Petran,

I'am meaning 20 ip-phones work (voice + signaling) on LSP and 190 freeze and never register on LSP.

This twenty ip-phone (4620sw 2.2) are in the same ip-network region 5 of 190 others.

one more time : Many Thanks

Regards

Michael
