Key Benefits of IP Telephony Not “one wire to the desktop. ” Not 300 bells and whistles. Four Revolutionary Features: - Computer-Telephone Integration (CTI) - Unified Messaging - Telecommuter/Branch Office Support - Web Based Administration You Can Do These on a TDM PBX. Bridging Two Worlds www. citel. com

CTI Make your PC and Phone work together: - Click-to-Dial - Call Logging + - Call Recording - Incoming Call Pop - Visual Call Control Bridging Two Worlds www. citel. com

CTI on TDM PBX Circuit Trunks PSTN TDM PBX USB or RS 232 CTI Adaptor Goes Between Phone and PBX, Connects to PC via USB. Also can use CTI server approach. $150 - $300 per seat. Bridging Two Worlds www. citel. com

CTI on IP PBX PC with Softphone & TAPI Trunks Gateway LAN 1010 PST N TAPI Interface Software within IP PBX CTI is implemented via software only. TAPI driver and softphone application on PC communicate with the IP PBX over LAN. No need for TAPI adaptor hardware because the IP PBX, PC, and phone all speak IP.

Unified Messaging Single System for Voice, Fax & E-Mail - See All Mail In One In-Box - Listen to Voice Mail via PC - Hear E-Mail via Phone - Respond to Voice Mail w/ E-mail and vice versa (reduce call-backs!) - Forward and Folder Voice Mail w/ E-Mail Bridging Two Worlds www. citel. com

Unified Messaging on TDM PBX Circuit Trunks PSTN TDM PBX Voice Adaptors UM Server External UM Server attaches via station ports. Requires station card in PBX plus voice cards in PC plus (sometimes) external adaptor and/or serial data link from PBX. Requires engineering effort for each model PBX.

Unified Messaging on IP PBX PC with UM Client Trunk Gateway Trunks LAN 1010 PST N UM Server Software On IP PBX Server IP PBX Unified Messaging is implemented in software only. IP PBX runs on standard server OS (UNIX, LINUX, Win 2 K) so UM can run on the same server. Or UM runs on its own server and communicates via an IP standard. No adaptors needed.

Web-Based Administration Open PBX Administration to Mere Mortals - Reduce Training For PBX Admin - Customer Self-Administration for MAC - User Self-Administration (speed dial programming, call routing capabilities) - Combined Admin of PBX, LAN, E-mail… Bridging Two Worlds www. citel. com

Web-Based Admin on TDM PBX Admin Server Admin Link Circuit Trunks TDM PBX PST N Administration Server Connects to PBX via Administration Link, Provides Web Interfaces and Unified Administration Bridging Two Worlds www. citel. com

Web-Based Admin on IP PBX PC with Browser Trunk Gateway LAN 1010 Trunks PST N Admin Server Software On IP PBX Server IP PBX runs on standard server OS (UNIX, LINUX, Win 2 K) so web server is built right in! Admin software just uses standard web application tools to control the various IP PBX settings Bridging Two Worlds www. citel. com

The Problem is the PBX TDM PBX Circuit Trunks PST N Call Control In a traditional PBX, the call control application is “locked” inside a proprietary platform, and tied to the media switching fabric. Other applications can’t communicate easily. Bridging Two Worlds www. citel. com

Having It All on an IP PBX Trunk Gateway Trunks LAN IP PBX Plus Applications WAN or VPN PST N LAN In an IP PBX, the call control application is separated from the switching fabric and becomes a typical data application on a standard server platform. Advanced software applications like CTI, UM, Telecommuter Support, and Web Admin are built in and can run on the same server platform. All the applications communicate in an IP structure. BUT it’s a total system replacement. Expensive! Bridging Two Worlds www. citel. com

Having It All via Handset Gateways Move to an IP PBX, Keep Your Phones One Side of Handset Gateway Has IP Interface to the IP Call Control Device IP Centrex Service Provider SIP IP PBXs 3 Com, Cisco, etc. Other Side Provides Power and Protocol Mapping to Existing PBX Handsets Bridging Two Worlds www. citel. com

Having it All via Handset Gateways Trunk Gateway LAN WAN or VPN PST N LAN IP PBX Plus Applications A Handset Gateway converts your existing PBX telephones into IP phones without doing a LAN upgrade or buying new phones. Can mix-and-match legacy digital phones with IP phones and migrate over time. Get the benefits of IP Telephony without the forklift upgrade. Bridging Two Worlds www. citel. com

Summary - IP Telephony Supports Applications - These Enhance User Productivity - You Can Do The Applications on TDM - Just Surround the PBX with Adaptors - You Can Migrate to an IP PBX - Get All the Apps by Replacing Everything - Or Migrate to IP, but Keep Your Phones - Get the Apps Without Replacing Everything Bridging Two Worlds www. citel. com
