Just getting started on 3CX -- looks very cool and well written. I'm trying to connect up a SPA3102 which is working quite well... I have it setup as a VoIP Gateway to my PSTN line and it works great. I can dial into the PSTN line and the SPA3102 forwards it on to 3CX which is routed to my IVR. Works flawlessly. What I want to do next is assign an extension in 3CX which will do the following: * HookFlash the current call on the PSTN line (which signals to my Comdial DXP to put the call in a holding area) * Next, I want to Send DTMF tones from 3CX to the call * Wait a few seconds for the tones to go through * Then simply hang up Doing the above will perform a transfer of the call through the Comdial DXP system as that the provider for my PSTN line and replace a very old prior system with 3CX which would be wonderful. Any guidance would be appreciated.
