Configuring Call Control Protocol - HP FlexNetwork MSR Series Configuration Manual

Step
2. Enter voice view.
3. Enter voice dial program
view.
4. Enter VoFR entity view.
5. Configure a PSTN-dialed
number in the FRF.11 trunk
mode.

Configuring call control protocol

Step
1. Enter system view.
2. Enter serial interface view.
3. Specify the link layer
protocol for interface
encapsulation as frame
relay.
4. Enter interface DLCI view.
5. Configure a VoFR call
control protocol on DLCI.
In the FRF.11 trunk mode, if the VoFR call control protocol is Huawei-compatible, the cid-number of
the channel to the destination host cannot be 4 or 5 because these two CIDs are already occupied by
the system. If the call control protocol is nonstandard-compatible, the cid-number of the channel to
the destination host cannot conflict with any data sub-channel 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.
Configuring trunk timer length in FRF.11 trunk mode
No signaling is exchanged in the FRF.11 trunk mode. After the terminating voice gateway in idle state
receives a voice packet, it considers that a new call is arriving. When one party hangs up, the other
party is not notified of on-hook through 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 within the trunk wait timer
length after on-hook, so that the party concerned can hang up successfully.
To configure the trunk wait timer length in the FRF.11 trunk mode:
Step
1. Enter system view.
