  1. TMC University’s Introduction to the IP-PBX “Reaping the Benefits of IP PBXs” Michael Robinson, CEO Citel Technologies www.citel.com

  2. Agenda What we will cover in this session: ▶ What is an IP PBX (and what isn’t)? ▶ What are the Benefits? ▶Rent versus buy ▶ Considerations in choosing a solution ▶ What we won’t cover in this session: Telling you what to buy Technical details in depth (covered later) 3

  3. What is an IP PBX? An IP PBX is a software application on a server. The IP PBX application is the directory service and traffic controller between “endpoints”. An endpoint can be a telephone (of many kinds), a handset gateway, device (e.g. PSTN trunk gateways), or another application (ie: voice mail). Critical distinction ⇨ the media stream (the voice) does not flow through an IP PBX. 4

  10. What are the Benefits? ▶Lower Operating Cost ▶Scalability and Disaster Recovery ▶Geographic Flexibility ▶ Next-Generation Features 11

  11. What are the Benefits? Lower Operating Cost Cheap long distance ▶ Pass calls over Internet or WAN between sites ▶ Route traffic over WAN to area of lowest rates ▶ Get cheap LD from an IP Carrier 12

  12. What are the Benefits? Lower Operating Cost Cheap long distance ▶Pass calls over Internet or WAN between sites ▶ Route traffic over WAN to area of lowest rates ▶ Get cheap LD from an IP Carrier Reduce number of business lines ▶Share trunks among sites (or centralize them) ▶Pay for a full T-1 plus 2 backup trunks per site (instead of 6 – 8 trunks per site) 13

  13. What are the Benefits? Lower Operating Cost Cheap long distance ▶ Pass calls over Internet or WAN between sites ▶ Route traffic over WAN to area of lowest rates ▶ Get cheap LD from an IP Carrier Reduce number of business lines ▶ Share trunks among sites (or centralize them) ▶ Pay for a full T-1 plus 2 backup trunks per site (instead of 6 – 8 trunks per site) Lower administration cost (esp. MAC) ▶ Web-based administration means less training cost ▶Allows remote and centralized administration ▶ Enables user self-administration 14

  14. What are the Benefits? Scalability and Disaster Recovery Software is inherently more scalable! ▶ Not limited by cabinet size for lines and trunks ▶ More devices can be added as needed ▶ Not limited by PBX processor capacity ▶ Clustered servers can add scale (like web sites) 15

  15. What are the Benefits? Scalability and Disaster Recovery Software is inherently more scalable! ▶Not limited by cabinet size for lines and trunks ▶ More devices can be added as needed ▶ Not limited by PBX processor capacity ▶ Clustered servers can add scale (like web sites) Mirrored servers can be miles apart ▶Same technology used for www and FTP ▶If one server goes down, devices “scramble” to another server and overall service stays up 16

  16. What are the Benefits? Geographic Flexibility No more 2500 foot limits on line length ▶ Both signaling (“features”) and media (voice) are passed over IP at any distance ▶ Phones and other devices all over the city and around the world can work as a single network ▶ Single dialing plan, central administration, shared resources and applications, etc. 17

  17. What are the Benefits? Geographic Flexibility No more 2500 foot limits on line length ▶ Both signaling (“features”) and media (voice) are passed over IP at any distance ▶ Phones and other devices all over the city and around the world can work as a single network ▶ Single dialing plan, central administration, shared resources and applications, etc. This enables several other benefits: ▶Cheap long distance ▶Mobility and Telecommuter Support ▶Disaster recovery ▶Hosting becomes a viable option 18

  18. What are the Benefits? Better Features What’s a “Feature”? Dial tone: Invented when?1890’s Make Call, Take Call (DOD, DID) 1890’s – 1940’s Hold, Transfer, Conference Music-on-hold, Paging, DND Caller ID, MWI, Multiple Line Appearances Call Forwarding, Bridged Lines, BLF ☞ Traditional PBXs Stuck Here 19

  19. What are the Benefits? Better Features Hold, Transfer, Conference Music-on-hold, Paging, DND Caller ID, MWI, Multiple Line Appearances Call Forwarding, Bridged Lines, BLF ☞ Traditional PBX Stuck Here Next-Generation Features ▶ Call Logs, Directory Dialing ▶ Instant Messaging ▶ Telecommuting, Simul-Ring ▶ Computer - Telephone Integration (CTI - a bundle) ▶ Unified Messaging (an application) ☞ IP Telephony Enables All These 20

  20. + CTI Make your PC and Phone work together: ▶Click-to-Dial ▶Call Logging ▶ Call Recording ▶Incoming Call Pop ▶Visual Call Control 21

  21. Unified Messaging Single System for Voice, Fax and Email ▶ See All Mail in One In-Box ▶ Listen to Voice Mail via PC ▶ Hear Email via Phone ▶ Respond to Voice Mail with Email and vice versa (reduce call-backs!) ▶Forward and Folder Voice Mail with Email 22

  22. Web-Based Administration Open PBX Administration to Mere Mortals ▶ Reduce Training For PBX Administration ▶Customer Self-Administration for MAC ▶ User Self-Administration (speed dial programming, call routing capabilities) ▶ Combined Administration of PBX, LAN, Email… 23

  23. Citel Gateway Web Administration System configuration options via web browser Easily configure telephones with pull down menus 24

  24. Telecommuter/Branch Support (a.k.a. “Voice VPN”) Enable PBX stations to be deployed over IP WAN or Internet. ▶Part or Full-Time Telecommuters ▶Small Branch Office to Metro Hub ▶Distributed Call Center ▶ Toll By-Pass ▶Coordinated Dialing Plan 25

  25. Eventually, you’ll want all these: ▶Computer Telephone Integration (CTI) ▶ Unified Messaging ▶Telecommuter / Branch Office Support ▶Web-based Administration You can do all these on a TDM PBX… ….at a price 26

  33. 1010 Next-Gen Features in IP PSTN Trunks 1010 Trunk Gateway ▶ Software can be spread across many devices. ▶ One company doesn’t have to make all the elements. ▶ Different elements can be placed anywhere. PC soft phone from Microsoft, Handset Gateway from Citel, phones from new IP PBX vendor, plus your old phones. 1010 LAN WAN or VPN LAN IP PBX Plus Applications 1010 34

  34. What are the Benefits? ▶ Lower operating cost ▶Scalability and disaster recovery ▶ Geographic flexibility ▶Next-generation features These all stem from “setting the software free”. Compare the pace of PBX feature development to the pace of Internet feature development. An IP PBX is asoftware applicationon a server. 35

  35. R LAN Server If Local LAN Deployment is an Issue: Re-use PBX Wiring CITELlink SIP Gateway for Nortel Meridian 1 and Norstar Handsets CITELlink SIP Gateway for Lucent Definity or NEC Handsets L A N IP Phone • User experience maintained • Less customer training • Mix in IP phones as needed • Re-use of phone focuses attention on • IP applications • Existing PBX work force can be leveraged A Handset Gateway converts your existing PBX telephones into IP phones without doing a LAN upgrade or buying new phones. Get the benefits of IP telephony at $140/seat instead of $600. 36

  36. Agenda What we will cover in this session: ▶ What is an IP PBX (and what isn’t)? ▶ What are the Benefits? ▶ Rent versus buy ▶ Considerations in choosing a solution ▶ What we won’t cover in this session: Telling you what to buy Technical details in depth (covered later) 37

  42. Rent versus Buy Traditional “Centrex” Limitations ▶ Relatively expensive compared to PBX ▶ Limited features compared to PBX ▶ Difficult to provision, long lead times for MAC ▶ Mainly attractive to <10 users or > 2000 users ▶Only has 10% - 14% market share vs. PBX 43

  43. Rent versus Buy Traditional “Centrex” Limitations ▶Relatively expensive compared to PBX ▶Limited features compared to PBX ▶Difficult to provision, long lead times for MAC ▶Mainly attractive to < 10 users or > 2000 users ▶Only has 10% - 14% market share vs. PBX IP Centrex ▶Costs are leveled (no wires, no class 5 switch) ▶Features are the same (it’s the same software) ▶Provisioning and administration are web-based ▶Expected to win 25% to 50% market share ▶Do you host your own web servers? 44

  46. Considerations in Choosing ▶What are you trying to achieve? Which benefits are driving your decision? ▶How will you get there? Does the solution offer a migration path? Can you protect your sunk costs? ▶Watch out for hidden costs LAN upgrade for QoS and PoE can be costly. Make sure the total cost is accounted for. ▶Should you buy or rent? Don’t make a knee-jerk decision on this. Hosted IP telephony is a real option. 47

  47. Summary ▶ IP telephony is compelling telephony because of the benefits it brings. ▶ Don’t be confused by VoIP noise. ▶Features and applications are the real drivers behind all PBX telephony. Be clear about what you want in your solution. ▶Consider the rent versus buy option, and look for a good migration option. 48
