35 Channel Maintenance
This chapter describes channel-related maintenance.
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
Call-ID: 1234@<srchost>
Event: soft-sync
➢ To enable remote call disconnect upon receipt of SIP NOTIFY:
1. Open the SIP Definitions General Settings page (Setup menu > Signaling & Media tab > SIP
Definitions folder > SIP Definitions General Settings).
2. From the 'Remote Management by SIP Notify' (EnableSIPRemoteReset) drop-down list,
select Enable:
3. Click Apply.
