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
