Configuring The Off-Hook Mode - HP FlexNetwork MSR Series Configuration Manual

To configure the duration before a forced on-hook:
Step
1. Enter system view.
2. Enter FXO voice
subscriber line view.
3. Configure the duration
before a forced on-hook.
IMPORTANT:
Once forced on-hook is enabled, calls will be automatically disconnected when the duration expires,
even if the conversation is going on.
Configuring the delay time before an on-hook
Usually, after the FXO interface detects a busy tone, the system automatically disconnects the call
and immediately removes the connection. When an FXO subscriber line is used as the VoIP access
port can cooperate with an IP phone, because the IP phone does not play any prompt tone to the IP
phone user, it is easily for the IP phone user to ignore the busy tone and considers that the line failure
occurs when the FXO subscriber line detects the busy tone and removes the connection quickly.
With the delay time before an on-hook configured, when the FXO subscriber line detects a busy tone,
it waits for a period of time, and then disconnects a call and removes the connection. In this case, the
busy tone is first sent to the FXO interface and then sent to the IP phone, and the IP phone user will
easily confirm the busy tone information before the connection is removed.
To configure the delay time before an on-hook for the FXO voice subscriber line:
Step
1. Enter system view.
2. Enter FXO voice
subscriber line view.
3. Configure the delay time
before an on-hook for the
FXO voice subscriber
line.

Configuring the off-hook mode

There are two off-hook modes after the FXO voice subscriber line receives ringing:
•
Immediate mode—The calling party dials the number of the trunk. Upon receiving the call, the
FXO goes off-hook and sends a dial tone to the calling party. Then, the calling party dials the
destination number.
•
Delay mode—The number of the private line is configured in subscriber line view on the
system. When the calling party dials the destination number, the call is routed to its destination
based on the configured private line number. When the called party picks up the phone, the
FXO goes off-hook for the conversation.
