I may be on to something with this issue. I want to see if anyone else can verify what I'm seeing.

It appears that sometimes the registration times out early, causing a brief period for every registration cycle, where calls will failover.

Example, if my registration timeout is 10 minutes, the voipo server seems to timeout at around 9 min 20 sec. So there's about 40 seconds where calls failover.

I can increase or decrease the timeout with the same result... just more or less frequent, but still leaving a downtime every cycle.

To verify this, I simply log into a control panel and hit refresh while watching the registration as the timeout approaches. Then sure enough, I see "no devices registered" message towards the end of the registration period.

Anyone else experiencing this?
