Yeah, my settings are good, I've been a long time customer (going on 6th year) with BYOD, first on PAP2T and now on SPA2102 and have not noticed this problem until the past few weeks. It sounds to me like we have the same issue, my failover setting is to go to VM which is exactly what is happening on sporadic incoming calls. Not sure if something changed on Voipo's side that would be causing this, but there is another thread here in the forums with 2 others having the same issue.
