Usage guidelines
This command has global significance. The configuration is valid for all FRF.11 trunk calls after the
command is executed.
The Trunk Wait timer is specific to the FRF.11 trunk mode. Within the trunk wait timer length, incoming
calls are prohibited and received voice packets are dropped.
No signaling is exchanged in the FRF.11 trunk mode. When one voice gateway receives the first voice
packet from its peer voice gateway over a dedicated voice channel, the former considers that a call is
coming. When either party involved in a call hangs up, the peer voice gateway (relative to the party who
hangs up) will still keep sending voice packets to the local voice gateway. Without the Trunk Wait timer
mechanism, the local voice gateway will immediately alert the party who has hung up so that this party
could never hang up successfully in the FRF.11 trunk mode.
Examples
# Configure the Trunk Wait timer length in the FRF.11 trunk mode to 40 seconds.
