1 to 10 8 (default)


When you enable this option, the phone first writes log files directly into its flash memory. The contents of the flash memory upload to a provisioning server after a predetermined period of time or when the flash memory becomes full. Poly recommends not changing this parameter.



1 (default) – Disabled

0 – The phone is prevented from uploading its contents from memory to the server. Disabling the ability to upload log files is recommended only when necessary to reduce data traffic when the phone starts or reboots.



1 (default) – Low power alert for rear USB port shows when phone is connected to Class-0 PoE. 0 – Low power alert for rear USB port is not shown when phone is connected to Class-0 PoE.

Set the time interval for the phone to send STUN binding request to the STUN server to detect whether NAT device is rebooted.


60 seconds (default) - The phone sends the STUN binding requests to the STUN server for every 60 seconds. If NAT IP address or the port details in the STUN binding response don’t match with the previous binding response, the phone automatically restarts.

  • - The phone doesn’t check whether NAT device is rebooted. If NAT device is rebooted and the

NAT IP address or the port is changed, the phone doesn’t receive any incoming messages as the IP address and port details published in SIP register message don’t match. You need to restart the phone manually to make the changes effective. Poly recommends not to set the value as 0 second.
