Ok - This may be my own ignorance, but I really would like to know why this happens, and why it made such a HUGE difference.
Just migrated a customer off of Hosted and onto my shiny-new all PJSIP FreePBX and no sooner did I have the phones provisioned (All Polycom 410’s) then they started cycling like MAD - literally seconds between unreachable/reachable over and over so much that the console was nothing but that - and only with 10 phones. Switched it to TCP and it went away instantly and has not even peeped for two hours.
Comcast Coax connection using Comcast as a router for all 10 endpoints - PBX is on a SDN Connection that is perfectly stable. I haven’t tried one of their phones away from their office, so I don’t know if they just have a flakey LAN, but if it was flakey, I would expect for the TCP connected-phones to cycle a little bit, but ZERO - it is 100% rock solid!!
Should I be doing TCP from now on? Why the HUGE difference?
