Re: [Freeswitch-users] DTMF with Early Media Disabled

Klaus Teller napsal(a):

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.

Really? It violates the law in most Europian countries :-) I think you are from Germany - if such a carrier does it, the best you can do is to contact your Telco Regulator (Die Bundesnetzagentur - www.bundesnetzagentur.de) and ask for official correction. Best regards, kokoska.rokoska
