Update June 2011: High latency remains - still not using ooma as my primary until it's resolved...
Signed up for ooma to replace Vonage as my usage is very light and my Vonage bill no longer justified (after almost 9 years). So this was a high bar to meet. I am not 100% happy with Ooma: Main gripe is high call latency - I can't come to terms with this but given the low usage I have for a phone these days it's 'good enough'. Second gripe: No email notification for VM unless you are on Premier (I don't need the VM attached but notification would be nice). Third grip: iLBC instead of G.711 - why anyone doesn't use G.711 in these days I don't know... Compression never sounds as good (even so this sounds as good as it get's for compressed). Overall a keeper...
