5.14.6 P25 Conventional Telephone Calls
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 pre programmed list only (direct
entry using the keypad is not allowed)
• Unlimited - Telephone numbers can be selected from a list and also dialed directly using
the keypad.
Both limited and DTMF keypad models can place telephone calls by recalling the
telephone number from a pre programmed list as just described. However, only DTMF
keypad models can directly dial telephone numbers using the keypad.
