Procedure to create 2 devices in CM using the same DN

[mohammednoor]

Hi,

I am currently having an issue associating 2 IP Phone devices - one a Cisco 7945 and the other a Cisco 7940 - to the same DN or extension number. The previous engineer was able to create the 2 IP Phone devices for another DN but when I tried to create a similar configuration following a user request, the second IP Phone booted up but the extension number was not displayed/activated. Also, the new device is not listed in CM or the Route Plan report.

Very much appreciate any solution. Thanks.

Regards,

Hi Noor,

Do not configure shared-line appearances on the  primary lines of the phones; for example, if two phones have a  shared-line appearance, only one of the phones should have the primary  line configured as shared (the other phone should have the secondary  line configured as shared).

Hi Ronak,

Thanks for the information. How do I detect the IP Phone that is not even displayed in CM after having added it as a device?

Hi Ronak,

When I do that it only displays the already working Cisco 7940. The newly added Cisco 7945 is not displayed at all.

Hi

Let me know following

1) What version of CUCM you are using

2) Are you getting any error while adding phone manually.

3) are you doing Auto regestration.

Hi,

CUCM is no version 7.1.3; the phone was added without any errors; I am not using auto registration.

I had to disable and enter static network information to allow the phone to download updates from the server. After that I had enabled DHCP and reset the phone.

Hi Mohammed,

You may have to restart folloing two services

Cisco RIS Data Collector
Cisco Database Layer Monitor

But please remember if this is production issue, raise TAC case before proceeding.

HiMohammed,

you have to make sure on the phone that it is registered to right call manager cluster or not.

if it is not showing on oneserver , try seraching it on other server or you cant find the phone is any of the server in the cluster?
