CUCM 8.6 Redundancy config

[Rajkumar Singaram]

Hi,

We have configured two CUCM version 8.6(2a) such as Publisher and Subscriber and we are facing some problems on this,

• •1.     IP Phone 7965G is not register with backup CUCM when primary goes down. But rest of the phone 6921 phone are able to register with Backup.

• •2.     We configured two CM group and Two device pool, But the device pool applied on the phone is not work as distributed call processing. All devices register with one CUCM.

• •3.     Also when the primary CUCM down it takes minimum 3 minutes to switchover, is there a way to reduce the switchover timing? Also need to verify where to configure primary and secondary CUCM?

Please find the attached CM group, device pool and phone screenshots

Thank You

Regards

This may be DNS issue, replace the CM servers hostnames with IP addresses in CUCM and try again.
