chan_dongle is third party code which doesn’t seem to have been touched in about the six years, and is documented as being of alpha quality, which normally means not suitable for even test use other than by the developer.
There is a good chance that no-one here can give you a definitive answer.
There appears to be a forum for it at https://groups.google.com/g/chan_dongle which might provide some more useful information.
One other point to notice is, not surprisingly, chan_dongle has no code to send AST_FRAME_DTMF frames to the Asterisk core. That is basically because mobile networks don’t support DTMF reliably, in the network to terminal direction. People have been caught out by this when they have found that IVRs don’t work with chan_dongle.
