Hi

I purchased a UC320W in January of this year and set it up here in the UK, with one FXO line and two SIP trunks from Sipgate. It had v2.3.2 installed.

On testing the initial configuration, I experienced problems with the system randomly disconnecting incoming calls and rebooting. I didn’t have time to undertake a detailed examination at the time, so I downgraded to the previous version of the firmware (2.2.2 (1)) and found the system to be extremely stable since.

Recently, I purchased a pair of SPA514G phones to add to the system, forcing me to upgrade to 2.3.2 (6) again. The problems have reoccurred – some incoming calls disconnecting and then causing the system to reboot.

I did a lot of investigation online and have found other users reporting the same problem, but couldn’t find any conclusive resolution.

I then did a detailed investigation on the UC320W and while I couldn’t see any consistency on incoming call behaviour, I managed to establish a consistent pattern around call DISCONNECTIONS. Whether the FXO call had been received or initiated didn’t make any difference to the results.

I found that when a call was disconnected from the UC320W side, it caused the system to reboot EVERY TIME. If the remote end disconnected the call however, then the system NEVER rebooted.

This led me to do an impedance test, which suggested changing the Impedance Value and the Line Type from “EIA 0” to “2000 ft 22 awg”. The results were the same, but I found that if I changed the Impedance Value to the one suggested and left the Line Type as “EIA 0”, the system performed very stably (perhaps 20-30 tests) with no rebooting on disconnection from either side.

Back to incoming calls however, I am still experiencing random disconnections and system reboots.

I’ve included a syslog extract of the most recent one.
