9. 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

10. 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

11. 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

12. 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

13. 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

14. 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
