Telephony Halo Effect Bundled customers have stronger perceptions of Cox than cable-only subs. 15

Telephony Survey Results n Customers rate Cox Digital Phone a 7+ on 10 point scale l l l n 88% satisfied with Cox Digital Phone service 95% likely to continue Cox Digital Phone subscription 91% likely to recommend Cox Digital Phone to a friend Cox customers favorably compare Cox Digital Phone service to previous phone provider l l 82% - better value for the money; 97% - same or better 62% - better quality of customer service; 92% - same or better reliability 94% - same or better call clarity, sound quality and accuracy of billing Telephone customers love us as evidenced by our outstanding customer survey results! 16

Telephony A Complex Business Choice of technology is easy, getting ready operationally to offer phone service is challenging Foundation of “lessons learned” prepares Cox for next step! Local number portability Interconnect agreements Universal service fund maximization Carrier access Trunk capacity management Directory listing and assistance E 911 Third party verification for LD Network powering Busy line verification Switch management & configuration Cox Local Switch Charges and Billing Number resource optimization When IP technology arrives, WE ARE READY! 17

Integrating Circuit-switched and IP Telephony Without Stranding Capital Chris Bowick, Chief Technical Officer 18

Key Take-Aways for Today n Our network infrastructure provides the foundation to support all new services and is prepared for the future. n Telephony is a very complex business with a steep learning curve, and Cox is well along that curve. n Vo. IP is not yet “ready for prime-time; ” but when it is, then we’ll be “more than ready”. n Vo. IP can be introduced in circuit-switched markets without stranding capital -- as a compliment or overlay to circuitswitched. n Cable. Labs’ DOCSIS 1. 1 and Packet. Cable standards will enable Vo. IP in non-switched markets. 19

Internet Telephony vs Vo. IP n Definitions l IP Telephony or Vo. IP • Private network(s), managed IP Backbone l Internet Telephony • Public internet (Net 2 Phone) Managed IP Network or NIU 20

What changes when Vo. IP is “ready for prime time? ” Why don’t you strand any capital? 30

Cox Digital Telephone Service Changes necessary to add Vo. IP in circuit-switched markets NOC Directory Assistance IP Backbone E 911 Operator Services • Upgrade the switch for <$10/line (XAcore, Succession) PIC/CARE switch capacity from 100 K to 150 K Lines LIDB • Expands Directory • Additional benefit, and eliminates stranded capital • Becomes a hybrid switch -- Vo.

Key Points To Remember n Vo. IP is not yet “ready for prime time” l l n No stranded capital in circuit-switched markets l n But when it’s ready, we’ll be well up the complex telephony learning curve And we’ll have the back-office infrastructure to support it Minimal switch-upgrade with additional benefit of increasing line capacity by 50% New telephone customers are Vo. IP (at our option) l l Existing circuit-switched customers only migrate if they want valueadded IP services Both Vo. IP and circuit-switched customers coexist happily in the same market We know the telephone business, and have the infrastructure to support it! 37
