Is there any way to implement consultive call transfer on FXS analog phone?
As far as I know MGCP allows only blind one - analog phone user presses 'flash' gets dial tone, dials target number and the call gets forwarded immediately. Is is possible to change this behaviour?
Another option could be controlling an FXS port with STACP application - has anyone tried to implement call transfer with SCCP analog gateway? How does it work?
