in my setup I am trying to forward calls on from my asterisk to a cell phone. The call goes out and reaches the cell phone and rings. However, if the receiver accepts the call the call drops straight away.
The Asterisk platform is Switchfin running stable on an Atcom device.
It seems that I can only utilize 1 line. Putting a call on hold and making a second external call is also impossible.
Has anyone an idea how to resolve this, please?
