Beginning about 10 days ago, we started having call quality and connection problems with outgoing calls using Google Voice. Intermittently, we'd have sound problems on connected calls. Then, we started receiving 503 errors when placing calls, so I checked for a firmware updated, and found that there was one available. I am now running 1.3.0 (Build: 2690).
Since then (and possibly merely coincidentally), 50% of the time, outbound calls ring but then there is silence. I've been able to reproduce the problem by calling my cell phone from my POTS phone connected through the OBI110. The problem does not occur when using a landline connected to the same line as the OBI110, but through a different jack.
Since this is a work line, this is impacting customer goodwill and I have gone from a very happy Obi110 customer to a very unhappy one.
