Just bought a small office with what appears to be a "hybrid" partner system--No ACS Processor Module-but a 206-R4.1 and a 206E-R3.1. I bought a MLS12 Display, since the 4 handsets I have are ACSs without displays. I have been successful in programming system time and date, but the system recognizes only 1 of 2 incoming lines. When I try to program Number of Lines #104, it appears to "take" #10 and then "stops". Line Assignment #103 does the same.
Any suggestions/help would be greatly appreciated. Located in Somerset County, New Jersey and would be glad to find a reasonably-priced consultant.

Well for one thing Line Assignment is #301 not #103. What exactly do you have in the system? need to know what processor and what cards. And what kind of phones are you using, so phones won't work with some systems (old and new systems) Then I can help you .
