Agenda

•What are Next Generation Networks?

•No analog lines? No ISDN? What now?

•Planning the migration

•Soft Migration

•Questions?

•Also known as All-IP

•Unified Communications (UC) based on IP telephony

•Common infrastructure for all telephony and data services

•Calls are usually established by the Session Initiation Protocol (SIP)

Next Generation Networks (NGN)

•Voice-over-IP

•All IP devices connected through the Local Area Network (LAN)

•No NTBAs, no splitters, no separate cabling

• IP easily connected and accessible

•Open standards instead of proprietary phones

•Free choice of phones

LAN now also does telephony

Free choice of phones

•Most common protocol for IP telephony

•Usually free choice of Internet Service Providers (ISP)

•Replace all types of analog and ISDN connections

SIP trunking

•Usually any number of lines and phone numbers can be booked

•Can usually be done by a click or call

•No additional physical connections required

•Numbers no longer wired and easily portable

•Additional foreign SIP trunks may reduce costs further

SIP trunking

•Recently bought phone system now to be replaced?

•High workload?

•How to include peripheral devices?

Why hesitate?

•Private Branch Exchange (PBX)

•Software IP phone system

•SIP trunks and IP phones registered trough LAN

•Actual location of the IP PBX practically irrelevant

•Decide: Hosted/Cloud PBX vs. Inhouse-On-Premise PBX

Choosing your PBX

•Running on an external server in a data center

•Accessed trough internet connection

•Pricing usually user-based

•Configured und maintained by hosting provider

•Lower initial costs + monthly rental costs

Hosted/Cloud PBX

•Running locally within the company

•Full access

•Higher initial costs but less running costs

•Decide: Virtualised or dedicated server hardware

-> Lower hardware costs or failure isolation

In-house/On-premise PBX

•Don’t rush

•State of telecommunication and network infrastructure

•Network configuration and internet connection

•Ongoing maintenance and service contracts?

•Decide: Continue using current hardware or completely switch to VoIP?

Planning the migration

•Keeping your old hardware?

-> Build a bridge

Planning the migration

•Network requirements

•Quality of Service (QoS)

•Power over Ethernet (PoE)

•Virtual local area networks (VLAN)

Planning the migration

•Define a time window for the migration

•Plan further development of telecommunication infrastructure

•Point out both short- and middle-term investments

•New technology leads to changing business processes

-> Training for end users

Planning the migration

•Don’t rush

•Changing business processes

•New requirements for end users

•Make a plan

•Use both systems in parallel for a transitional period

Soft Migration: Pilot Phase

•Choose the least critical department to start using the new setup

•Train the employees

•Choose next department to proceed

Soft Migration: Implementation

•New IP PBX and legacy phone system are running in parallel

•Gateway connects PBX to legacy phone system, analog or ISDN devices and providers

•Proprietary phones replaced by IP phones

Soft Migration: Outcome
