Does your question is ooh323c should check Progress-Indicator? or
Did you mean ooh323c to generate ALERTING message with Q.931 Progress
Indicator Element?

I guess, ALERTING means ringtone stage, There is no fake ringtone/Alerting.
Or you can says fake, if other end phone ringer is not working ;)

Here:
GnuGK <-------  [ ooh323c - asterisk core - SANGOMA FXO(PSTN interface)]
<---- PSTN

So in Asterisk internal dealing (PSTN to H.323 conversion):
Sangoma indicates to Asterisk Core (ringing).
