There has been improvement in the quality of LiveVoip connections. Still some packet loss and resultant choppy audio, a little worse than with Vonage or Broadvoice. As noted in several posts over the past months, they still don't handle indication of ringing on an IAX channel if the caller has dialed a number in the Asterisk switch (for instance with the DISA app). The workaround previously suggested, to Answer() and then run Ringing() doesn't work in this case, because it still sends the IAX command for ringing which LiveVoip doesn't recognize. However, Playtones(ring) does work and represents a usable workaround for the price. They claim to be working on a new session controller that will fix this and other problems. We'll see.
