7962 with 2 Expansion Modules

[mlong0000]

Hi

I am having a problem configuring the buttons for 2 expansion modules. I have a 7962 configured. Creating a phone button template I can only configure 36 buttons but physically I have 54 buttons (6 on phone, 24 on exp mod 1, 24 on exp mod 2).

So I can configure the first expansion module which is being used for monitoring lines. The second expansion module is being used for speed dials but I can only configure 4. Im not entirely sure where the others are going.

I am running CallManager 6.1(3)

Anyone been through this before?

Sorry, I meant above that I can only configure 34 buttons. The rest show up on the phone config page as "Unassigned Associated Items"

Hi Michael,

Here are the details for this issue.

Cisco Unified Communications Manager 4.2(3)SR3a, 4.3(2), 5.1(3)b, and 6.1(1), 7.0 and 7.1

From this 7916 Data Sheet;

http://www.cisco.com/en/US/prod/collateral/voicesw/ps6788/phones/ps379/data_sheet_c78-468673.html

I believe you are hitting this bug which has only been fixed in certain 6.1(3) versions;

CSCsx47243

CUCM 6.1.3 Phone Button Template for 7962/7965/7975 Shows 34/36 line.

Symptom:

On CUCM version if you have a 2 7916 extension module on7965 and 7975 the Phone Button template is not capable of 42 lines as per Document we can only ad 34/36 respectively.

Conditions:

When you want to add the 2 7916 extension modules to the Ip phone 7965 /7975 Phones we can not make 42 line Phone Button template for those Phones.

Workaround:

No Work around

Hi Rob

thanks for the detailed reply. I actually made a mistake when I put down the CM version. We are actually running 6.1.4.1000-10

Should be fixed in this version........

However the phone firmware is only 8.4

Going by a table in that link I need 8.5(3) onwars.

Hi Michael,

Yes, you are most correct my friend

The added button support was only included in 8.5(3) and later firmware. I don't

believe 8.5(3) is available as it was deferred due to some funky bugs. Make sure to

check the Firmware release notes to see what Add-on module firmware is required

for compatibility

Hi,

I have CUCM BE 8.0.3 and i have one 7962 with two 7915 modules (24 keys each).

Only 7915 near phone is working the other nodule doesn't show any keys configured it only show cisco Logo. I have created a phone button template with 54 keys.

and in device phone i have configured two 7915 24 keys module.

Original 7962 firmware with these version of CUCM BE is SCCP42.9-0-2SR1S  also tried to upgrade phone to latest version of 7962 firmware 9.1(1)SR1
