Is there any way to make classic extension to emit DTMF?
The recipient of would-be classic extension is reachable as an extension within other PBX, so I have to dial the number, wait, and then dial the destination extension number.
It can be done, but it has nothing to do with DTMF.
What is actually required, is a pause to be added after the first dialed string. So the PSTN_Number of the Classic extension should be XXXXXXXXXXXXXXpXXX where the "p" represents a pause. In case more time is needed add more pauses.
