Trade offs


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)
