If Asterisk is configured for FXO signaling (not port type), then that
means it is expecting to be providing battery and ringing to the other
endpoint, since it would the FXS *port*. In this configuration, when a
channel is dialed, the port will be put into ringing state, and if
configured, Caller ID will be sent. No digits will ever be sent unless
done after the call is up by an application.

If, on the other hand, Asterisk is configured for FXS signaling, it is
acting as an FXO port, and thus under normal circumstances a digit
string would be sent when calls are placed on those channel. This is
under control of the dialplan, though... using Dial(DAHDI/4) without
adding an extension to dial after it would cause chan_dahdi to go off
hook, skip sending any digits, and go into 'answered' mode.
