hello all i am using teliax as a voip provider and i cannot get dtmf signals to go over their service. i was told that they use dtmf 2833 and i put that in my iax.conf and sip.conf and it still does not work. i can call extensions and my voicemail and it works fine. Just when making calls over iax it does not work. Any ideas?
here is my iax.conf
