Jim, I look in zaptel.conf and fxogs=1 # TX pair I changed this to fxogs=2 # TX pair I then look in zapata.conf under Repeater TX Channel = 1 I changed it to Channel = 2 Went back to zaptel.conf and fxols=2 # RX pair. I changed this to fxols=1 then went back to zapata.conf under Repeater RX Channel = 2 I changed it to channel = 1 And rebooted the machince, called asterisk back up and the red LED went out. I hope this is right but if not please tell me. Anyway, it's been on for quite some time. Now the next problem is getting the audio up and going. There is still no dtmf detection. please advise. Thanks Will / W4WW
