Have a M1 that I am trying to network with a BCM50. Trouble is, I can dial from my 50 to my M1 but get a reorder (fast busy)when I dial from my M1 to the 50. Have a point to point T-1 within same city. Programmed trunks as E&M tie with wink signaling. I do a trace at the M1 side when I make a call and it shows me hitting the correct route and sending out the correct number but I get the FB as soon as I dial the number. We are the local provider so I put a t-comm tester on my T-1 and proved that I only hear the first digit and then gets the FB. Like I said it's works fine one way. Any ideas???
