The actual switch from ISDN is easier than you might think, and there are transitional options if you're not ready to switch off capital expenditure. The first step is to ask yourself a few questions around the business:

  • How many phones numbers do you have?
  • Where do those numbers lead?
  • Are incoming calls queued or directed elsewhere if the line is busy?
  • What kind of voicemail system does your business require?

Once you've established the basics, take a look at the top 5 things you should consider when upgrading your phone lines to SIP from ISDN. At the top of this list is managing your number porting process and making sure you allow for the time required to do this seamlessly – this is critical given the copper switch-off.
