Phone Registration to CUCM

[scooter817]

    Hi everyone

I wanted to know if someone can help me with this issue that I'm having. I have a new intallation of CUCM in our NY office as a SUB, but when you input a phone it's registering back to your Georgia Subcriber instead of the one in NY.What  do I have to do to make the phones that are in the NY office register to the subscriber there on site instead of the Georgia sub. Thanks inadvance for any help and as all ways have a great day.

You need to adjust the CUCM group that those phones get via the device pool.

Configure the servers in the order on which you want phones to register to them.

Hi Scooter,

+5 to Java ...just thought might help as well;

The registration relationship is built via the Callmanager Group and Device Pool that the phones belong to.

You  can specify where a phone registers by assigning it to a specific  Device Pool this in turn will look at a Callmanager Group that lists a  Primary, Secondary and Tertiary Callmanager server.

Here is some related info;

Cisco  Unified CallManager groups and device pools represent logical groupings  of devices that you can arrange in any way that you want. For ease of  administration, make sure that all the devices in a group or pool share a  common and easily identified characteristic, such as their physical  location on the network.

You  can also use Cisco Unified CallManager groups to establish redundancy  (backup call processors) for the primary Cisco Unified CallManager in  the group. A Cisco Unified CallManager group comprises an ordered list  of up to three Cisco Unified CallManager servers. During normal  operation, the first (primary) Cisco Unified CallManager in the group  controls all device pools and devices that are assigned to that group.  If the primary Cisco Unified CallManager in a group fails, control of  the device pools and devices that are registered with the primary Cisco  Unified CallManager transfers to the next Cisco Unified CallManager in  the group list.

Cisco Unified CallManager Groups

A  Cisco Unified CallManager group comprises a prioritized list of up to  three Cisco Unified CallManagers. The first Cisco Unified CallManager in  the list serves as the primary Cisco Unified CallManager for that  group, and the other members of the group serve as secondary (backup)  Cisco Unified CallManagers.

Cisco  Unified CallManager groups associate with devices through device pools.  Each device belongs to a device pool, and each device pool specifies  the Cisco Unified CallManager group for all of its devices.

Cisco Unified CallManager Groups:

Call  processing load balancing You can configure device pools and Cisco  Unified CallManager groups to distribute the control of devices across  multiple Cisco Unified CallManagers. These should be Subscriber servers

Device Pools

Device pools provide a convenient way to define a set of common characteristics that can be assigned to devices.

Cheers!
