Re: help required in outgoingcall (Slightly modified)

Beel,

What provider are you using?

Some analog line providers have a problem doing "line discrimination",
that is detecting when the user has answered the call, since PSTN analog
(POTS) lines don't send any easily detectable signal to identify this --
you really need low-level silence detection to guess at the call
progress state. If the JTAPI layer doesn't know the Connection has
connected, it may not allow the playing of audio.

Cheers,


Richard
