- Cloud phone system with new numbers: usually a few business days once the information and the contract are confirmed.
- Local numbers in other countries: three to five business days in the normal case, after the availability study and with the documentation in order.
- Porting of United States numbers: the carrier that hands over the number sets the timeline.
- WhatsApp Business: it depends on your company's verification with Meta.
- SMS on Toll-Free numbers: verification usually takes one to three weeks.

Implementation includes setting up menus, queues, schedules and users, training your team and running tests before real traffic is switched over.
