2 days ago I would pickup the phone on the 1st-2nd ring and there was no answer. Little did I know that caller had already left a message after the 4-5th ring. I figured it was GV acting up. Today I used my Groovip and received calls just fine,,, aha the Obi's fault. I did the usual testing , router, obi etc. and reloaded a previous months config for obi & router,,, the same problem. Just for giggles I back loaded firmware to 1-30-0-2669,, works beautiful,, went forward to 1-30-0-2675 . Still working fine 2 hrs.
I will update if there is any changes.
