I'm assuming that you are using SIP/IAX trunks? If so, then you change the DTMF mode via the 'dtmfmode' directive in your trunk configuration page. If you are using an AT&T mobile phone, your DTMF will most likely experience issues like the ones you've stated above. There are some known issues with the DTMF handling from AT&T wireless phones.

Because we are using 2n easygate gsm modem and direct connect as pstn line to tdm410p card.And it have frequency problem.We find out that if we was using pstn link and call from mobile phone.It was working fine.
