SoundPoint IP321 'rebooting', suspect network but need to quantify

I have a number of PolyCom IP321 and IP331 phones deployed and have been having weird issues with a very small number of them that I have been unable to pin down.  I have updated the firmware on them (went very well) and have done all that I can to pin the problem down but I'm at a loss on how to proceed.  Below is an overview of the setup and a condensed timeline:



- Asterisk PBX 

- Provisioning of phones done via FTP from the PBX

-- All phones are on the same LAN as the PBX 

- All phones use A/C adapters and not PoE



- Shortly after install (appx 1.5 years ago, at thissss point), some of the phones began 'rebooting'

- We checked all of the obvious, power, connections, etc.

- As a test, we replaced the phones with my phone (had never 'rebooted') and neither phone (mine or the one that we put at my desk that was rebooting) rebooted.

- One other phone 'rebooted' a few months ago but never came back online.  I went to that location and confirmed that the switch that it was plugged into had died (the user had plugged the phone into a workgroup switch with 2 other devices and the workgroup switch had failed).  We replaced the switch and have had no more problems.

- Now, two other phones on the same network are beginning to reboot.  I am not opposed to swapping out additional phones but would like to see if there is some way for me to 'see' what's going on on the Polycom phones.  I see notices in the PBX log (it's FreePBX, so the log is /var/log/asterisk/full) stating that the phones are lagged and / or unreachable) but I do not have any log data on the phones to tell me if they became lagged / unreachable *before* they 'reboot' or if the lagged / unreachable was the reason for the reboot, etc.

Hello cybertechcafe,

welcome to the Polycom Community.


Without knowing your current updated software level checking against release notes is difficult.


I would suggest you check your phones boot & app log possibly using a syslog server as described in the FAQ => here <= in order to check for any errors mentioned in the log.


Quite often users using the wrong files (sip.cfg/ phone1.cfg) or simply wrong parameters causing the phone to reboot.


It is also interesting in what state the phones reboot (idle / busy) and if this can be reproduced. 

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
