The setup is Modem/Router - Allworx 24x and 6x - switch - 9212 phones
The problem slowly started happening without any changes/updates other than changing a modem/router combo unit even earlier than the problems began.
For DD, I temporarily tested the new unit in "unsecure mode" by opening up all ports, disabling firewall, etc. to see if any 24x traffic was being blocked/dropped and the bad behavior persisted.
So here are the bad behaviors:
- Phones go offline randomly displaying can't load config files (red mute/DND) - softkey reboot does not fix, only unplugging power will fix
- Phones will not connect to internal extensions - some will after 5-10 second wait, some never connect (sometimes external lines too)
- Phone will randomly infinitely ring if call is missed and caller hangs up - have to cycle the receiver cradle button to stop the ringing
I am open to suggestions - I'm guessing the 24x is going bad? I can't find any other network component that is experiencing issues and other network functions are normal.
Also, the phones that experience this are random...I don't see a pattern.
Thanks for the help.
