Cofiguring Cisco 7915 extention module in CME

Confiuring a extention Module in CME is pretty straignt fowards:

First of all you need to check the compatibility of the Phone and the Extension Module and then Also check the firmware compatibility

Second step is to copy the Firmware file to flash  the below command can be used

Copy tftp flash:

Next define the tftp-server command in global config mode:

tftp-server flash:B015-1-0-2.SBN

Next define the Load command under telephony-services

load 7915-12 B015-1-0-2

* Remember to exlude the .sbn extention.

Next go to the ephone and type the below command

ephone 20
type 7962 addon 1 7915-12
Configure the additional Line

* i spent around 5 hour to make the Extention module register to the CME only because i haven't created the cnf file again so make a note that sometime you may need to create a cnf file again in telephony-service
