Soft Migration


If a company is faced with the decision to renew its PBX-infrastructure, from today’s perspective a VoIP system is the first choice. VoIP systems offer many advantages such as lower maintenance costs, higher compatibility between different manufacturers and a higher functional range; which improves communication efficiency.

At larger companies with more than 100 devices this change is done through a soft migration. The soft migration allows the company to run the classic PBX system parallel to the new VoIP system. By doing so, the functionality of the new VoIP system can be thoroughly tested in an isolated part of the company.

This kind of migration is executed in 5 phases:

  • Test phase
  • Pilot phase
  • Migration of the excisting accessory devices to the VoIP system
  • Successive migration of all the departments
  • Deconstruction of the classic PBX devices and infrastructure

After the second phase, the so called Pilot phase, all departments will be individually migrated to the new system. This ensures that every department receives proper instruction on the new telephone system, so that it is better accepted by the employees and used more effectively.

This document discusses the different scenarios and challenges of a soft migration.

All-IP Transformation


All IP is the new buzzword of the telecommunication industry. But what will the consequences of replacing ISDN networks with ALL IP networks, especially for owners of classic PBX systems? Short reminder: All IP is a complete IP based access which will soon be converted from Analog or ISDN to IP / SIP.

VoIP offers many possibilities:
  • Cost savings
  • Higher compatibility
  • More features
  • Faster installation of new workplaces

When migrating to a new VoIP provider the following three challenges need to be considered:

  1. Compatibility with the existing phone system
  2. Capacity of the internet connection
  3. Further use of older devices and special services

This Whitepaper discusses these challenges and provides possible solutions.
