I killed the land line service to house and M1G threw a phone line error. I attempted to disable the phone backup in Telephone 1 and 2 and must have done something wrong because CO now says no heartbeat. What are correct settings for T1 and T2? June 15, 2024 at 1:15 pm #8077 James Thornburg I have T1 set for 6=IP and 1 dialing attempts, (didnt change M1XEP settings) I have T2 set for disabled. Is this OK or do I need to delete T2? June 17, 2024 at 5:59 pm #8080 Brad Weeks T2 set to Disabled is fine but also look under Globals G01 – G05 to make sure Telephone Remote Control is set to 0 = Disabled June 19, 2024 at 12:13 pm #8086 James Thornburg It wasnt so thanks!
