[FAQ] Reboot the Phone remotely or via the Web Interface

The current UCS 4.0.0 Software added this functionality to the compatible Polycom devices via the Web Interface.

Via a SIP Check-Sync NOTIFY


Prior to UCS 4.0.0 Software and still current Software the method:


<voIpProt voIpProt.SIP.specialEvent.checkSync.alwaysReboot="1" />


can be used to remotely reboot the Unit if it receives a SIP Notify Message that contains the event equal to check-sync.


From: <sip:test>;tag=1530231855-106746376154
To: <sip:>
Call-ID: b98cd3c4-f37c265b-c864532
Contact: <sip:test>
Event: check-sync
Max-Forwards: 10
Content-Length: 0


The standard value of this functionality is usually:




  • If set to 1, always reboot when a NOTIFY message is received from the server with event equal to check-sync.

  • If set to 0, only reboot if any of the files listed in <MAC-address>.cfg have changed on the FTP server when a NOTIFY message is received from the server with event equal to check-sync.



NOTE: Many SIP Platforms (Asterisk / Broadworks) have solutions for this included and the WWW Community can be used to find example Perl or Python scripts on how to use this.
