We have created a step-by-step migration checklist for you.
We are going to assume that you have chosen SIP Lines to replace ISDN
This depends on your business. Do you have more than one site? Or even several floors of an office building?
SIP can work alongside ISDN so it can be done in phases.
Only if you are doing the phase out before the actual switch off of ISDN (in 2025).
This is a large chunk of the process because the supplier and installer (hopefully us) will need to work out several factors such as:
* How many sites do you have?
* How many SIP lines do you need?
* Do you have the right amount of available bandwidth?
* Are your current handsets compatible with SIP?
* How many phone numbers need porting?
There is less infrastructure than ISDN but there is still set-up to be done, even down to reconfiguring the phones (physical handsets and softphones) and porting the phone numbers over.
The main part of any new installation is good testing to ensure it all runs smoothly and doesn’t hinder any business operations.
SIP comes with built-in resilience and business continuity features but you need to ensure that it all fits within your DR plan and it actually works.
Time to turn the new system on. As long as the other steps have been followed, it should all go smoothly.
