Telephone calls can be placed and received on P25 conventional channels. This feature 
allows telephone calls to be placed and received over the public telephone system using 
your radio. Telephone calls are programmed to operate in one of the following modes:

• Disabled

• Answer-only capability

• List only - Telephone numbers can be selected from a preprogrammed list only (direct 

entry as follows is not allowed)

• Unlimited - Telephone numbers can be selected from a list and also dialed directly 

entered using the front panel controls or the keypad on the HHC.

All models have the capability to place telephone calls by recalling the number from a list 
or dialing it using the front panel controls or using the Handheld Control Unit (HHC) 
telephone keypad. More information on how to do this follows.

P25 conventional telephone calls utilize an access to access the system when placing a 
telephone call, and a de-access code to terminate the call when it is finished. These codes 
are preprogrammed in pairs by the Access/De-Access Code list selected on the 
conventional Per System screen, and up to 16 pair can be programmed. Each conventional 
P25 channel can be programmed to automatically select one of these code pairs. They 
must match the system codes, and the default code is *1P# (the P represents a pause).
