We have a site with a MICS 7.0XC installed that is out of ports. Considering adding a second MICS using a T-1 connection for additional ports. Does anyone have experience with this type of an application that can provide some "caution" and "beware of" items that would be good to know before jumping into this? We have a CallPilot 150 with 112 seats loaded. AA is used by the site. Planning to add more seats. PRI is in place with plenty of DID - range 2000 thru 2199 and a second range not used yet of 2500 thru 2799 that we're planning to put on the second MICS. DN match the last four of the DID numbers. In addition to the points of caution, I do have a concern with target lines. Will I receive another batch of 223 target lines with the second MICS or am I limited to what is on the first system? Thanks.
