When incoming DATA call arrive on ISDN BRI, asterisk (zaphfc) recognise type of call, but answering anyway (playing IVR messages, ringing phones, etc...) How to stop that? I want that only VOICE calls are answered, and DATA/FAX to be ignored. (I'm using Asterisk 1.2.1 Brisftuffed 0.3.0-PRE-1f, ZapHFC) Log: -- Accepting data call from 'XXXXXXXX' to '3001' on channel 0/2, span 1 -- Executing Answer("Zap/2-1", "") in new stack -- Executing BackGround("Zap/2-1", "ivr_intro") in new stack
