I use the same logic to send out DTMF signal after connection.
I use SP2 to connect my asterisk box at extension 6109.
Here is my extension.conf
[CallingRule_obi110]
exten => _816XXXXXXXX,1,Set(GLOBAL(hkno)=2**8${EXTEN:3}#)
exten => _816XXXXXXXX,n,Dial(SIP/6109,,D(${hkno})r)
When I press 816 + HK No, the dialplan will process and then dial out via OBi110 to PSTN line connect
Same logic will allow you to connect GV and OBiTalk Circle of Trust |
