Quick question on IP phone registration... 2

[BrokenBear]

Greetings Tek-Tips gurus,

I have a question about IP phone registration concerning ESS mode.

I have 2 sites - one on the east coast and one out west. The east coast site is the main site and the western office is the ESS site. Each site is running CM6 on an HP DL360 with 2 G650 gateways.

Our network team was doing some maintenance one weekend and our phone system went into ESS mode. The CM server at the main site was unavailable for a little while so the IP phones at the main site registered to the ESS site.
When the main CM server came back online, we executed the get-forced takeover command and came out of ESS mode. When I checked the socket status, most all the phones in the main site were still registered to the ESS site's CLAN cards - I had to manually restart all the IP phones at the main site so they would re-register to the main site (procr).

My question is, would the phones have automatically re-registered to the main site after a predetermined amount of time or is a manual restart of the phones necessary? Is there a timer setting somewhere?

Not sure if it matters but all IP phones in the main site register procr and IP phones in the ESS site register to a CLAN onsite.

Thanks everyone!

I believe that option might just be the Periodic Registration Timer.

Check the CM screen reference. For that periodic registration timer, 20 means once every 20 minutes for two hours, then once an hour for 24 hours, then once every 24 hours continually.

Maybe you needed to wait a bit longer? Or maybe get some more details about the network outage and compare/contrast with precisely what you would have expected.

Recovery rule maybe?

Thanks for the replies, Kyle and smokin' Joe. It could be that I should have waited longer.
I didn't see much in the Recovery Rule screen, but in the ip-options screen, the recovery timer is set to 20 - I guess that's the default.

While I'm here, I have another ip phone registration question:

Sometimes I use my One-x Communicator when I'm at my desk even though my 9611 phone is here as well. I have noticed that SOMETIMES when I log out of one-x, my 9611 phone re-registers. Other times, it does not. What would cause the 9611 to not register after I log out of One-X?

Road warrior and telecommuter modes will logout your desk station. 'control of phone' mode won't logout your 9611. Maybe you go between working from home and the office and didn't notice?

Also, you`d probably want to review your survivability settings top to bottom for ESS and stuff. You need to reconcile H248 gateway recovery rules, port network communities, etc. There`s also a nifty feature that forces phones to the ESS for network regions that have gateways registered to the ESS - basically trying to keep clusters of things together when in a failover. The long answer to your issue of phones staying registered is a lot of review!

It depends on a couple of things.

1. Did you have port networks or media gateways still registered to the survivable server? If so the phones won't automatically return. You could have disabled network region registration in the ESS server to force the phones to unregister from the ESS server.
2. There is a "known issue" in some of the 6.x releases where this occurs. You can check the Release Notes. If I remember correctly it talks about 10 stations.

If you are using IPSI connected port networks I would recommend using CLAN registration. Keeps things together.
