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.
