1 Introducing the Cisco Unified
IP Phone Expansion Module 7915
The Cisco Unified IP Phone Expansion Module 7915 attaches to your Cisco Unified IP Phone 7962G, Cisco Unified
IP Phone 7965G or Cisco Unified IP Phone 7975G, adding up to 24 extra line appearances or programmable buttons to your phone. Attaching a second Expansion Module to your
Cisco Unified IP Phone adds a total of 48 extra line appearances or programmable buttons to your phone. See Figure 1.
Note If you are running the SCCP protocol, you can configure a maximum of 42 lines on your phone. For example, if you configure two 24-line Cisco Unified IP Phone Expansion Modules on a Cisco Unified IP Phone 7962G or Cisco Unified IP Phone 7965G, you will have a total of 54 lines (48 lines from the modules in addition to the 6 lines on the phone). However, only the first 42 lines will be available for use.
The programmable buttons can be configured as phone line buttons, speed-dial buttons, phone service buttons or phone feature buttons.
