I bought an IAXy just about a week ago, and I'm having a problem with it. I provisioned it without any problems. It's on the same network segment as my Asterisk server. It registers just fine. When I call from the IAXy to a Zap channel, it works fine. When I call from a Zap channel to the IAXy, I don't get any audio from the IAXy, only from the Zap to the IAXy. Near the beginning of the call, I get some warnings on the Asterisk console about dropping slin frames because we've already switched to ulaw. No other warnings or errors. What could I be doing wrong? What other information can I provide that would be helpful? This is a pretty straightforward configuration, I would have thought... Rob
