I have installed a call pilot 150 on a norstar mics. The customer has 4 lines that app&ring on 6 phones. They want 2 mailboxes. They want lines 1&2 to ring no answer to mailbox 222 and lines 3&4 to ring no answer to mailbox 224. The only way I was able to make that work is to have lines 1&2 app&ring on ext. 222 and lines 3&4 app&ring on ext. 224. That won’t work because they want all lines to app&ring on both phones. With this line assignment all calls go to mailbox 222. Is there a solution to my dilemma? Thanks.
