After six months and two VoIP adapters I have never had reliable service. Calls drop at random times, audio drops out for several seconds, the audio quality is bad and lately, when I get an outside call all I here is a busy signal. When people call me they hear a ring tone but my phones do not ring, or they get a message "All lines are busy." When I contacted the SageVone service people I made appointments to talk with technical experts that were never kept. In six months I have never talked to a technical person. Their service representative was rude and abusive and blamed everyone except himself for the problems. They kept blaming my broadband service even though I sent test data showing that there was no problem on this end (6.5Mb/s isn't enough?!?). They also told me that their service is incompatible with MacOS and Linux systems. Something that they do not advertise. In my opinion, this is not a company to be trusted or patronized.
