VoIP- What is the Cost of Reliability? Hybrid Phone System’s Advantages and how to avoid the pitfalls. Presented By: E astern T elephone & T elecommunications

What is VOIP Telephone service over data networks Transporting voice conversations via data packets Utilizes the ubiquitous Internet Protocol Hence Voice Over IP

Benefits of VOIP Cost Savings for Long Distance Calls Converged wiring infrastructure “ Go anywhere ” telephone Connect with WAN or Internet Leverage Internet Use private WAN or public Internet

How it works Place Call Compress Packetize Transmit Receive Buffer Decompress Answer IPNetwork

What it is not Not a complete stand-alone voice solution Independent of other systems 100% guaranteed throughput

Pure IP Network Solution Call Mgr.. Voice Mail TI/PRI Gateway Analog Trunk Gateway Analog Sta.Gateway All switching and call processing are done by separate control units connected over the data network, adding unnecessary bandwidth issues.

Reliability Issues Bandwidth Required vs Bandwidth Available Quality of Service (QoS) Stability of Customer Data Network Reputation of Installer and Equipment Changes to Data Network

Some VOIP Pitfalls Poor Voice Quality Consumption of Network Bandwidth Security Issues Multiple points of failure Emergency 911 calls may fail

What the Experts are saying! “ There is no one architecture (yet) that can be called the standard for a network phone system. The important thing is to follow a strategy that makes sense for your business. Trashing your PBX and going all IP immediately probably isn ’ t it. ” Bill Michael - Computer Telephony

What the Experts are saying! “ The underlying assumption regarding ToIP is that the LAN/WAN is always available, with minimal downtime. This is a very risky assumption, because no LAN/WAN infrastructure is currently designed to meet the % reliability level of a PBX system. ” Alan Sulkin - Telecom Industry Consultant

The Hybrid Solution Builds upon proven technology Forward and backward compatible Implements architecture appropriately Delivers advanced features and benefits Provides smoothest migration Brings choice of technology to customers

The Hybrid Advantage Integrates TDM and VOIP Telephony Return On Investment (ROI) TDM components continue working during data network failures Can integrate via T1, fiber, ATM, Frame Relay, or data network VOIP Supports analog, digital, and/or VOIP telephones simultaneously
