Sure - really, what you are running into is a difference in how Asterisk
bridges channels:

I suspect the reason DTMF is not decoded is because you are in a native
bridge (local or remote). You can force a core two-party bridge by
requiring that Asterisk decode the media and detect DTMF. Those
requirements are done by setting the various 'feature' flags on whatever
dialplan application is causing the channels to be bridged. For an example,
see the 't' or 'T' options in Dial:
