Remotely Resetting Device using SIP NOTIFY

The device can be remotely reset upon the receipt of a SIP NOTIFY that includes an Event
header set to 'check-sync;reboot=true', 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 Advanced Parameters page (Configuration tab > VoIP menu > SIP
Definitions > Advanced Parameters).
2. Under the Misc Parameters group, set the 'SIP Remote Rest' parameter to Enable.
3. Click Submit.

Locking and Unlocking the Device

The Lock and Unlock option allows you to lock the device so that it doesn't accept any new
calls and maintains only the current calls. This is useful when, for example, you are
uploading new software files to the device and you don't want any traffic to interfere with
the process.

To lock the device:
1. Open the Maintenance Actions page (see ''Basic Maintenance'' on page 561).
2. Scroll down to the 'LOCK / UNLOCK' group:
3. From the 'Graceful Option' drop-down list, select one of the following options:
•
Yes: The device is locked only after the user-defined time in the 'Lock Timeout'
field (see Step 4) expires or no more active traffic exists (the earliest thereof). In
addition, no new traffic is accepted.
•
No: The device is locked regardless of traffic. Any existing traffic is terminated
immediately.
Note: These options are only available if the current status of the device is in
UNLOCKED state.
4. If you set 'Graceful Option' to Yes (in the previous step), then in the 'Lock Timeout'
field, enter the time (in seconds) after which the device locks. If no traffic exists and
the time has not yet expired, the device locks immediately.
