2. The calling party dials and the voice interface card collects and stores the dialed digits, that is, 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 this is a new call.
