Adaptive line key allocation for key expansion modules

An apparatus, comprising:

• a telecommunication device that has a line key display;
• a processor operatively coupled to the telecommunication device;
• and
• a memory resource operatively coupled to the processor, wherein the processor is configured to execute instructions to:
• store, in the memory resource, a list of line keys for visualization on the line key display;
• determine a first set of line keys from the list of line keys to display on the telecommunication device when a key expansion module is coupled to the telecommunication device and a second set of line keys from the list of line keys to display on the key expansion module when the key expansion module is coupled to the telecommunication device;
• determine whether the key expansion module is coupled to the telecommunication device;
• cause the first set of line keys to be displayed on the telecommunication device when the key expansion module is coupled to the telecommunication device;
• and
• cause the second set of line keys to be displayed on the key expansion module when the key expansion module is coupled to the telecommunication device.

A tangible, non-transitory, computer-readable medium storing program instructions that cause a device to execute a process comprising:

• storing a list of line keys for a phone that has a line key display;
• determining a first set of line keys from the list of line keys to display on the phone when a key expansion module is paired to the phone and a second set of line keys from the list of line keys to display on the key expansion module;
• determining whether the key expansion module is paired to the phone;
• displaying the first set of line keys on the phone when the key expansion module is paired to the phone;
• and
• displaying the second set of line keys on the key expansion module when the key expansion module is paired to the phone.
