What is PnP?
Plug and Play (PnP) is a method for IP phones to acquire the provisioning server address. With
PnP enabled, the IP phone broadcasts the PnP SUBSCRIBE message to obtain a provisioning
server address during startup. Any SIP server recognizing the message will respond with the
preconfigured provisioning server address, so the IP phone will be able to download the CFG
files from the provisioning server. PnP depends on support from a SIP server.
System Log Issues
Why can’t I export the system log to a provisioning server (FTP/TFTP
server)?
Do one of the following:

Ensure that the FTP/TFTP server is downloaded and installed on your local system.

Ensure that you have configured the FTP/TFTP server address correctly via web user
interface on your IP phone.

Reboot the phone. The configurations require a reboot to take effect.
Why can’t I export the system log to a syslog server?
Do one of the following:

Ensure that the syslog server supports saving the syslog files exported from IP phone.

Ensure that you have configured the syslog server address correctly via web user interface
on your IP phone.

Reboot the phone. The configurations require a reboot to take effect.
Resetting Issues
Generally, some common issues may occur while using the IP phone. You can reset your phone
to factory configurations after you have tried all troubleshooting suggestions but do not solve
the problem. Resetting the phone to factory configurations clears the flash parameters, removes
log files, user data, and cached data, and resets the administrator password to admin. All custom
settings will be overwritten after resetting.
Six ways to reset the phone:

Reset local settings
: All configurations saved in the <MAC>-local.cfg file on the IP phone
will be reset. Changes associated with non-static settings made via web user interface and
phone user interface are saved in the <MAC>-local.cfg file.

Reset non-static settings
: All non-static settings on the phone will be reset. After
resetting the non-static settings, the IP phone will perform the auto provisioning process
immediately.
