Why?
• Campus saturated with mobile devices Faculty, staff and students increasingly mobile
Students disinterested in campus telephony
• Diminishing office & meeting room space
• Physically dispersed, “time shifted” work force • Overloaded Email storage (file management)
• Cost of supporting multiple vendor solutions: Email
Voicemail
IM & conferencing
• Interest from many directions to move to VoIP
Underlying Factors

Telephony Lessons Learned
• Study your telephony dial plan
Be prepared to modify the PBX dial plan
We use 5 digit and 10 digit dialing
• No E911 Support from OC ClientConsider having users sign a “waiver” document
• Watch voice mail rollover ring time
Could affect “Sim Ring” or “Forward to”

Project Lessons Learned
• Senior Management support a necessity• Engage deep level PBX vendor support
• Target “highly communicative” pilot groups
• Use department specific “real world”
demos to generate enthusiasm
• Develop business case based on new
value, not cost savings
