Number Porting

Number porting moves your existing phone numbers from your current provider over to your new system, and it’s scheduled at cutover (the moment your service officially switches over — see Glossary) so there’s no gap where your numbers stop working.

How long does porting typically take?

It varies by number type and current carrier — often a couple of weeks for standard business lines, though it can be faster or slower depending on your existing provider’s process. We’ll give you a realistic timeline once we know your specific numbers and carrier.

Do our numbers stop working during the porting process?

No — your existing service keeps working normally right up until the scheduled cutover moment, at which point calls seamlessly start arriving on the new system instead. The goal is zero downtime, not a gap while the port is “in progress.”

Can we schedule exactly when the cutover happens?

Yes — porting can typically be scheduled for a specific date and time, or left to complete whenever the carriers process it, depending on what your business needs. Many businesses schedule it for an evening or weekend to minimize any disruption risk.

Can we port a mix of number types — local, toll-free, and numbers from different carriers?

Yes — each number is ported individually, so a business moving 30 local numbers from one carrier and 5 toll-free numbers from another can have all of them land on the new system, even if they don’t all complete on exactly the same day.

What if we’re also switching from an old on-premises phone system, not just a carrier?

Number porting is one part of a bigger migration in that case. See Migrating From Your Current Phone System for the fuller picture, including what happens to your existing hardware and phone system.
