phone_dial Dial The Telephony Interface
Description
This command dials the specified string of digits on the telephony interface.
This parameter can be used to dial one digit at a time or many digits all at once.
For the PSTN interface, valid digits are '0' through '9', '*', '#', and ',' (delay).
If the telephony interface is not connected (see the phone_connect parameter)
when this parameter is set, the digits will not be dialed. The phone must be
taken off hook by setting phone_connect to 1 before the digits can be dialed.
Examples
set phone_connect
"Phone Out" 1 val phone_connect
"Phone Out" 1 Takes the phone output channel "Phone Out" offhook.
Note that the phone out virtual channel name must be
used, not the phone input virtual channel name.

"Phone Out" 0 val phone_connect
"Phone Out" 0 Hangs up the phone line associated with the virtual
channel "Phone Out". Note that the phone out virtual
channel name must be used, not the phone input virtual
channel name.
