Establishing a migration plan, will include the following points:
• Ensure your current PBX supports SIP termination, if it doesn’t support SIP you will need to go out and buy a SIP gateway. This is just an IP voice to PSTN convertor; alternatively, you could just buy a VoIP PBX.
• Move existing lines and numbers to the new IP system (local number portability). Make sure you have the extension plan documented so that so that you can use this to configure the new IP service.
• Go slow – Move a single business line, then test it before committing your important sites to the migration.

1.2 Structure your network and introduce VLANS per extension
This step will entail the transition from the existing telephone structure to an IP cable infrastructure. There are two options here, either to use the existing data network cabling if there is any for data and voice or run a separate infrastructure purely for voice. It is advisable to opt for the latter for better quality calls.

1.3 Test the Cabling
Testing both jitter and latency are important in order to ensure clear quality and minimal delay.

1.4 Make sure your security is up to scratch
