Hi,
I have an intercom extension that can trigger opening of a gate by pressing number "8" when the channel is open.
I am trying to create advance routing that will trigger the following event.
Dial ext 360
wait for 3 sec
Dial DTMF tone (number

.
After the extension is dialed and channel is open, the DTMF tone is not playing.
Anyone can advise?
Thanks.
