an agent should wait in an confroom and hear some music or tones. On an website he should put in an tel number for calling to somebody. This is working wih phpagi very well.
I have problems with Agent should hear ringing when callee is called, busy for may be 5 s that callee is busy or congestion
I have problem when agent is the leaving before callee, that hangup should send to callee channel.
Also habe somebody an source for an soundfile with every 5s an beep that agent is hearing when he is the only person in confroom.
