CM 5.1 7915 Problem

Unanswered Question
Jan 20th, 2010


I have a 7915 Sidecar attached to a 7962G and it will not boot it it stuck on Orange Lights.

I have read many posts about device and sidecar OS versions so I have upgraded to the following, but the problem has not been fixed:

Here are the versions I am running:

Call Manager - [i.e. 5.1 (3c)]

7962G - SCCP42.8-5-3S

7915 - B015-1-0-4

The phone's webpage shows no Expansion Module attached.

This is happening on two phones so I don't think it is faulty equipment.

Another small issue, is that I am not sure which of the following options I should set the expansion module to in CM, as far as I know there is only one module and it has 2 pages of 12 buttons:

7915 12-Button Line Expansion Module

7915 24-Button Line Expansion Module

In any case I have tried it with both options without success.

Has anyone experience of my problem? Can anyone advise me how I can go about troubleshooting?

Many Thanks


I have this problem too.

I might be wrong.  But I don't think the CUCM version you're running recognize 7915.  You should try to download the latest device pack and install it on CUCM.

Hope this helps!
