Disconnecting Active Calls; Remotely Disconnecting Calls Using Sip Notify - AudioCodes Mediant 800 User Manual

CHAPTER 44 Channel Maintenance
● "In Service": Indicates that all channels in the Trunk Group are in service, for example,
when the Trunk Group is unlocked or Busy Out state cleared (see the EnableBusyOut
parameter for more information).
● "Going Out Of Service": Appears as soon as you choose the Lock button and indicates
that the device is starting to lock the Trunk Group and take channels out of service.
● "Going Out Of Service (<duration remaining of graceful period> sec / <number of calls still
active> calls)": Appears when the device is locking the Trunk Group and indicates the
number of buys channels and the time remaining until the graceful period ends, after which
the device locks the channels regardless of whether the call has ended or not.
● "Out Of Service": All fully configured trunks in the Trunk Group are out of service, for
example, when the Trunk Group is locked or in Busy Out state (see the EnableBusyOut
parameter).

Disconnecting Active Calls

You can forcibly disconnect all active calls, or disconnect specific calls based on Session ID.
➢
To disconnect calls through CLI:
■ Disconnect all active calls:
# clear voip calls
■ Disconnect active calls belonging to a specified Session ID:
# clear voip calls <Session ID>

Remotely Disconnecting Calls using SIP NOTIFY

The device can be triggered to disconnect all current calls upon the receipt of a SIP NOTIFY
message containing an Event header with the value 'soft-sync' (proprietary to AudioCodes ), as
shown in the example below:
NOTIFY sip:<user>@<dsthost> SIP/2.0
To: sip:<user>@<dsthost>
From: sip:sipsak@<srchost>
CSeq: 10 NOTIFY
If the device is reset, a locked Trunk Group remains locked. If the device is reset
while graceful lock is in progress, the Trunk Group is forced to lock immediately
after the device finishes its reset.
When the device is in High Availability (HA) mode:
✔
After an HA switchover, a locked Trunk Group remains locked.
✔
If an HA switchover is initiated while a Trunk Group is in locking progress, the
locking process is stopped and only starts again (with the configured graceful
period) once switchover completes.
✔
When HA status is in "Synchronizing" state, the Trunk Group status is not
updated in the Trunk Group Settings table. In addition, the lock/unlock actions
cannot be invoked during this time. When HA synchronization finishes and HA
status is in "Operational" state, the Trunk Group Settings table is refreshed
with the lock/unlock status. The HA state is displayed on the Monitor home
page.
