I have the 24-channels of the T1 setup in Line Pool A, and the phones programmed for Pool A as their Prime Line. When they go off-hook, they get an available line from the T1, but no dialtone -- just dead air. The calls do still go through.

AT&T (their carrier) says they can change from Wink-Start to Tone-Start, but the MICS does not have that option. I was wondering if maybe it was something with AT&T's switch, or maybe I missed something in the admin programming. (FYI: The T1 & MICS are set for B8ZS & ESF.) What else am I missing???
