Three Forms IP-enabled Converged IP IP only PBX core with optional VoIP Converged IP Combined VoIP and PBX core IP only IP core

IP Enabled Pros Mature, reliable backbone Feature rich core Strong protection of existing investment IP growth at a managed pace Disruption of staff is minimized Most popular approach for large existing installations

IP Enabled Cons Limited IP scalability PBX core will ultimately limit the applications Incremental IP station growth may cost more Benefits of a converged infrastructure cannot be fully realized

Converged IP Pros Usually based on established software Strong Features IP scales more cost effectively Usually supports digital expansion Lends itself best to blended IP and digital Great for planned migration Most popular for new system deployments and same vendor migration plans

Converged IP Cons Not ideal when used in one extreme or another (IP vs. Digital) Newer IP-based applications may still have limitations (varies by vendor) Scalability of IP at the desk still limited

IP Only Pros Scales very easily Management usually designed for the data administrator Tends to use more open standards for interoperability Least amount of geographic dependence Greatest long term opportunity for new application features Most popular for new site installations with strong IT staff

IP Only Cons Support for digital desktops almost non-existent Analog connectivity more costly due to conversion technology Migration options limited Transition is most costly and disruptive
