I think of 2 answers for you.
1) Get a Call Pilot - that will do it for you.

2) Since you don't want a Call Pilot then do this.
Line 1 rings to x 221 - after 3 rings goes to VM box 221
Line 2 rings to x 222 - after 4 rings goes to VM box 222
Line 3 rings to x 223 - after 6 rings goes to VM box 223

Problem solved - no "canned Sally" to say anything - that is only if you create a Answer Prompt for each voice mail box
Of course change the number of rings for your needs before going to voice mail.
AND if you need to see all 3 lines on the phones, just make them appear only except the one that rings on that phone
And when the other phone rings they can hear it and push the line button to answer if they have to answer.


If CON is the opposite of PRO
Then what is the opposite of Progress?
