I'm sorry. I'll try explane it more detailed.
There is such design: PSTN ->isdn-> AS5350 ->voip-> c3825/CME4.3
Now we use onramp script on the 5350. But we want to use this script on the 3825.
Is there any abilities to initiate the onramp script on the 3825 by the use of incoming call from the 5350? Or may be there another application to receive and convert faxes for our case?
