Creating VoFR Entity

No signaling exchange is involved in FRF.11 trunk mode. The following shows the
call flow in the FRF.11 trunk mode, with the first four steps being the same as
those in the dynamic mode:
1 The calling party picks up the phone. The voice interface card detects the off-hook
action, plays dial tones to the calling party, and waits for the calling party to dial a
number.
2 The calling party dials and the voice interface card collects and stores the dialed
digits, namely, the called number.
3 Upon the completion of dialing, the voice gateway matches the called number
against voice entities.
4 VoFR processes the call if a VoFR entity is matched. The processing method
depends on the call mode configured for the VoFR entity.
5 In the FRF.11 trunk mode, the originating voice gateway directly goes into the
conversation state and sends voice packets to the terminating voice gateway over
the voice channel in the FRF.11 trunk. The codec with the first priority is used for
voice compression and decompression.
6 After receiving the voice packets, the terminating voice gateway finds the
corresponding VoFR entity according to the voice channel in the FRF.11 trunk, and
uses the PSTN-dialed number that is configured for the VoFR entity as the called
number to complete the call.
7 After the call setup is successful, both the calling and called parties can
communicate.
8 When either party hangs up, the VoFR module on the local side does not ask the
peer side to release the call, but discards the voice packets received over the voice
channel in the FRF.11 trunk within a certain period of time. If the VoFR module
receives voice packets after this period of time expires, the VoFR module considers
that there is a new call.
