1) How many lines and phone extension do you have at this moment?
2) How much future growth do you need or not need for the system?
***Most important question 3) What is the application? What do you do; and what do you want the system to do for you?
4) Are there any special needs or wants for the new system?
5) If you are considering VOIP (internally) have you considered if your network can be used or does it also have to be upgraded etc?
