Agenda  Basic elements of an IP system  Optional elements of an IP system  3 forms of IP systems  Major areas of impact  Trade offs

Basic Elements  Call control  Signaling between elements  Core features  Integration point  IP/TDM conversion  On-net/off-net  Simple data exchange  User’s point of contact  Devices  Applications

Agenda  Basic elements of an IP system  Optional elements of an IP system  3 forms of IP systems  Major areas of impact  Trade offs

Optional Elements  Software applications  Workflow  Customer care  Collection/storage/data mining  Legacy interfaces  Digital and analog phones  Paging systems  Fax/modem connections  Media processing  Conferencing  Conversion  Collection

Agenda  Basic elements of an IP system  Optional elements of an IP system  3 forms of IP systems  Major areas of impact  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)  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

Agenda  Basic elements of an IP system  Optional elements of an IP system  3 forms of IP systems  Major areas of impact  Trade offs

Major Impact  Organizational goals  Increase revenue  Streamline operations  Control costs  User productivity  Adoption  Efficiency  Effectiveness  Administrative efficiency  Staffing  Uptime  versatility

Agenda  Basic elements of an IP system  Optional elements of an IP system  3 forms of IP systems  Major areas of impact  Trade offs

Trade Off  Depth of features vs. scalability  Performance  Topology  Manageability vs. capability  Correlation of user and admin complexity  Diametric goals  Sophistication vs. cost  Short term and long term objectives  Need vs. want  Burden and opportunity

Conclusion

 Basic elements of an IP system  Call control  IP/TDM conversion  User’s point of contact  Optional elements of an IP system  Software applications  Legacy interfaces  Media processing  3 forms of IP systems  IP enabled  Converged  Pure IP

Conclusion  Major areas of Impact  Organizational goals  User productivity  Administrative efficiency  Trade offs  Depth of features vs. scalability  Manageability vs. capability  Sophistication vs. cost
