Remotely Resetting Device using SIP NOTIFY

The device can be remotely reset upon the receipt of a SIP NOTIFY that contains an Event
header that is set to 'check-sync;reboot=true' (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: check-sync;reboot=true

To enable remote reset upon receipt of SIP NOTIFY:
1. Open the Gateway Advanced Settings page (Setup menu > Signaling & Media tab >
Gateway folder > Gateway Advanced Settings).
2. From the 'Remote Management by Notify' (EnableSIPRemoteReset) drop-down list,
select Enable:

Locking and Unlocking the Device

You can lock the device so that it stops processing calls. This may be useful, for example,
when you want to upload new software files to the device and you don't want any traffic to
interfere with the process. Locking the device may be done gracefully, whereby the device
stops accepting new calls, but allows existing calls to continue for up to a user-defined
duration before terminating them.

To lock the device:
1. Open the Maintenance Actions page:
•
Toolbar: Click the Reset button.
