[cisco-voip] Phone Restart on Subscriber add

Mon Apr 27 16:01:52 EDT 2015

It’s not a full reboot, looks just like an apply config, just enough for users to complain.

I'll have to lab this up and see what I am missing; last week I added a 9.1.x cluster node and I didnt get any phone bounces during the install.

Strange.

Thanks,

Ryan

So building the subscriber resets all phones in cluster to download updated Trust List?

It has nothing to do with adding subscriber to the CallManager group the phone is using?

I’ve heard of this issue but wasn’t clear (or forgot) about the specifics.

There's an option during the install to just check connectivity and then wait for the full install.  That's as far as you can go without resetting all the phones unfortunately.

Yes, I do understand that. I just need to know when in the install, The customer doesn’t want a 4 hour maintenance window to install a new node.

It happens when the cluster becomes aware of the new nodes certificates.  It adds a new TVS entry to the ITL of each node and resets the phones to ensure they download the new ITL before any other ITL changes are made.  This is to prevent too many changes happening the ITLs at once making the phones not trust the new ITLs.

All,

I have a customer that is very picky on when phones will reboot when adding a new subscriber to a CUCM cluster.

Does anyone know in what point the phones reboot? Right after the conntivity vierfication? Right when the new node is done installing?

Thanks
