[Freeswitch-users] DTMF with Early Media Disabled

I know it works perfectly when pre_answer is called. That is, when early media is activated. I was just trying to figure out what is the expected behavior when pre_answer is not called.
I want to get DTMF from users without having them billed by their carriers. I've heard that some carriers start billing as soon as early media is on. That's why i was wondering if DTMF (inband or out of band) can be received without answering or pre_answering.
