Frequently asked questions
Can we keep our PBX and change only the carrier?
Yes. Carrier replacement is usually the lowest-risk change: trunks are built in parallel, tested, then traffic is moved route by route.
How long does porting take?
It depends on the losing carrier and country. The plan assumes weeks, not days, and keeps the old service live until the port completes.
What about redundancy?
A second carrier on a lower-priority route, tested by deliberately failing the primary rather than assuming it works.
