Send DTMF with CFD to incoming call

[maxkessler]

Hi,

I know this Thread: https://www.3cx.com/community/threads/sending-back-dtmf.66405/

I want basically the same. An incoming call (identification call) is routed to a CFD App. Then the app should wait a few seconds and send the # key.
The trick with an recorded # key sound does not work. I have searched the CFD documentation but have not found anything about sending DTMF.

It could be a couple of things, either the recorded DTMF tones are not accurate enough to be decoded, or the DTMF Method is not correct at some point.

The CFD cannot SEND DTMF, it can only receive them.

In the linked thread someone wrote, it depends on the receiver if such "fake DTMF" are received properly.
My primary question is rather: Is there a noch-hacky way to send DTMF keys?

Okey, ConceptsWeb gave the answer.
This is sad..

The fake sounds would work if DTMF were set to "in audio" but 3CX uses RFC so it doesn't work the same way.
