Presentation Outline Existing telephone & network infrastructure General migration strategy VoIP pilot project First production implementation VoIP challenges Conclusions Q & A
Existing Voice Infrastructure Ericsson MD110 PBX –www.ericsson.com/enterprise/products/md110.shtml Installed in early ‘80s On-going upgrades – BC11 (supports Ericsson IP phones) Meets our needs: –Distributed –Flexible –Reliable –Scaleable –Roadmap to IP Telephony
Existing Network Infrastructure Cisco network with 20,000 hosts Core: GE, No multicast, No QOS Distribution: 100MB & GE Edge: –Primarily 10MB switched –Some switched 100MB and GE –Cat3, Cat5, or 5E, future Cat6 –No power-over-Ethernet (POE) Limited power backup systems
General Migration Strategy Leverage MD110 Learn and gain experience –Train staff –Compare/evaluate vendor solutions –Watch industry trends and standards –Learn from experiences of others Select a vendor solution Migrate to VoIP - No “forklift upgrade”
VoIP Pilot Projects Evaluating Cisco and Ericsson solutions Ericsson IP phones –Easy to integrate, but status quo –Weak market share Cisco Pilot –Cool looking user-friendly phones –Interoperability issues –Strong marketshare
1st Production Implementation Cal(IT) 2 - Telecom Research Building October 2004 100% Cisco IP phones –50-100 phones High-end Cisco network Backup power system An extension of our pilot project
VoIP Challenges Making a business case Identifying value-adding applications Selecting a vendor Cost of properly designed network Cost of hardening power
More VoIP Challenges Interoperability issues Network security All voice & data ‘Eggs’ in one basket The ‘bleeding edge’ ?
Conclusions IP Telephony the way of the future Cisco vs Ericsson vs others Forklift vs migration IP phones in new buildings Network upgrade and power backup costs are high Must have a good business plan
