7914 Expansion Module Corrupt Display

My customer has a 7914 expansion module that was working fine until a recent call manager upgrade to version 3.2.2c (spG). Now the display is corrupt, although the device is working fine. I tried the expansion module in the lab, with our call manager which is running the same version of software and I don't have any problems in the lab. My call manager has most of the service parameters still set to default but I suspect some of these have been changed at the customer site. Are there any service parameters that would effect the expansion module? Also, the phone load id is P00303020215.

Re: 7914 Expansion Module Corrupt Display

Maybe the 7914 template is corrupt. You can try this procedure to see if it fixes your problem, but you will need to make a change in SQL.

1 - From Device > Phone Button Template copy the 7960 template to a new template. Rename this to something like "New 7914"

2 - Use SQL Enterprise Manager to open the PhoneTemplate Table within the CCM30x database that is being used

3 - Find the record for "New 7914" and set the numOfButtons field to 14 and the tkPhoneTemplateUsage to 1

4 - Go back to the Phone Button Template Configuration screen, reload that template and configure as needed

5 - Select the "New 7914" for the Expansion Module

Re: 7914 Expansion Module Corrupt Display

Thanks for the info and apologies for the delay in getting back. I fixed the problem by downgrading the phone load to the last version that worked then upgrading again and now the 7914 display is fine.
