I’m having problems with making call transfer work:
A calls B
A puts B on hold and calls C
B picks up the phone and all three can speak
PROBLEM: when B hangs up, A and C loose communication
I’m quite new to asterisk and even not sure if this scenario is possible (B hangs up, A and C keep talking). If it is a possible scenario, please could anyone direct me to a manual or give a hint where to start looking.
It not pure “conferencing”. The fourth member wouldn’t be able to join. I guess what I have acheived so far is a three-way-call. The problem is that when the middle man (B) hangs up, the other two loose communication. This scenario works in our office with a regular (non-voip) PBX. So it might work with asterisk as well.
Regarding the telephones. I’m working for a cable network. So we are connecting regular phones to Scientific Atlanta EMTAs (which are cable modems with integrated ATAs).
