[cisco-voip] Cluster setup with 2 Subs - Sub 2 did not pick up the load.

[Gary_Bates_Command_Solutions]

Hi Nathan

 

Thanks, I replied to Bernhard already on the same points.

We are running 8.5 so there is no network setup page on the phone web page.

 

All Device pools are referencing the 2 CM groups. Both Groups have listed both subs.

 

Regards

 

Gary

Which Servers are included in the Server Group which is selected in the Device Pool assigned to the Phones?  When you mention 'TFTP Server lists', I'm assuming you mean the IP Addresses included in DHCP Option 150?  This is seperate to the CUCM Servers that are pushed to the phones.

 

But assuming all servers are included in the CUCM Server Group assigned to the Device Pool, the phones should have failed over upon loss of communication with their primary (and possibly) secondary CUCM Server.

 

Take a look at the web page of a phone and under the 'Network Setup' page, see what are set for 'Unified CM 1', 'Unified CM 2' and 'Unified CM 3' are.

My client had an issue where the 2nd sub did not register any phones when the Pub and primary Sub failed.

 

This is a 1500 seat call centre so it caused a massive problem.

 

All phones have the IP addresses of both subs in their TFTP server lists. Network routing confirmed ok. Call Manager / TFTP service running on both Subs. DB replication status good.

 

Could someone confirm that if Pub / Sub 1 go down, Sub 2 should allow phone/ device registration and calls to still work ?
