To specify a maximum time for transmitting or receiving a voice packet, use the timeout ptt command
in voice-port configuration mode. To return to the default, use the no form of this command.

Command Modes Voice-port configuration
Command History
Usage Guidelines The timeout ptt command is available on an ear and mouth (E&M) analog or digital voice port only if
the signal type for that port is Land Mobile Radio (LMR). The purpose of this command is to limit
extended radio transmission. When the time limit configured with this command expires, the radio
transmitter unkeys, so that listeners on the channel cannot hear the speaker, even if the speaker continues
to talk. When the speaker unkeys the radio, the timer is reactivated.
Examples The following example specifies a maximum time of 10 minutes for transmitting a voice packet:
voice-port 1/0/0
timeout ptt xmt 10
rcv Applies the specified time limit to the reception of voice packets.
xmt Applies the specified time limit to the transmission of voice packets.
minutes Maximum time, in minutes, allowed for transmitting or receiving a voice
packet. Range is integers from 1 to 30.
