number or signaling sub-channel number. In the FRF.11 trunk mode, the
Motorola-compatible protocol is not supported.
In the FRF.11 trunk mode, two voice entities (one VoFR entity and one voice
■
entity of any type) must be configured at each end of the trunk. The
PSTN-dialed number of the VoFR entity must be consistent with the
match-template of the other voice entity.
No signaling is exchanged in the FRF.11 trunk mode. Once the terminating voice
gateway in the idle state receives a voice packet, it considers that a new call is
arriving. When one party hangs up, the other party will not be notified of on-hook
via signaling messages, but will still keep sending voice packets. In this case, if the
voice gateway on the side of the party who hung up does not discard these voice
packets, but considers that they come from a new call, then the party who just
hung up will be alerted again so that on-hook could never succeed.
You can configure the voice gateway to discard the received voice packets the
trunk wait timer length after on-hook so that the party concerned can hang up
successfully.
