Ok, so I have some tricky programing and need some help. Customer has 15 Polycom ip560's he has 4 companies running out of one office. He wants each phone to use the line button as a company phone trunk line. Example: Ext 3000 picks up phone and hits button labeled "company 2"(the button for physical line 2) but what we want to happen is when he places that call it goes out on Company 2' trunk with Company 2's caller ID. Ext 2000, picks up phone and hits button labeled "company 3" (physical line 3), call goes out on trunk 3 with caller ID for company 3. I hope this makes sense, with my knowledge and logic I can't figure how this would be done. PLEASE ADVISE!!!
