I have both an HT802 and an HT 502 that at times peoples voices in either direction will cause the ATA to generate a DTMF digit to be generated as a person speaks. It happens more with specific people and phone calls. Is there some parameter (or other suggestion) that I can set where the ATA will timeout thinking that it should be dialing or generating DTMF tones? Thanks for any help or suggestions. Jim.
