DP750 and DP720 Firmware: 126.96.36.199
I have a problem where suddenly none of the handsets will ring on an incoming call (configured as parallel). The 750 is responding 486 busy. Calls during this time do show in the missed calls log though.
The only way to fix the issue is to reboot the 750.
I captured a syslog of the issue. Here are some relevant clips…
When this happens, all handsets look normal - the missed call indicator shows up on them. Rebooting the handsets has no effect.
I realize now that I only have this issue on the devices I have 188.8.131.52 installed on. I have not seen this issue on my 184.108.40.206 devices.
Has anyone else seen anything like this? Thanks!
