VoiP Auto Unregistering


Using UCM62xx and GWX410x.
1 analog line acting as VoiP with UCM automatically unregisters after some time (mostly after a few weeks).
Whenever I restart the GXW410x , the line registers automatically.
There are 3 lines connected to the GXW410x, 2 GSM and 1 Analog line. I’ve specified each channel as ch1:1-6 and ch2:7-8

What can be the problem?


Are both devices up to date on firmware?
Can you ping the GXW and get into the web GUI when unregistered?

Have you done a packet capture from the UCM to see if the device is sending requests?
