Three Forms

IP-enabled 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
