Getting started and switching.
What happens from your first call to go-live, and how to switch without downtime.
How does setting up a 3CTel phone system work?Setup follows four guided stages: plan, review, configure and test on a temporary number, then port and switch over. Nothing is billed before activation.Can I switch phone providers without losing calls?Yes. Your new system is built and tested on a temporary number while your old service keeps ringing, then your number ports across on a scheduled date.What should I prepare before moving to a new phone system?A checklist for switching: your latest phone bill, a list of numbers and users, how calls should route, internet details and who signs the port form.Do I need desk phones, or can I use apps only?You can run entirely on the desktop and mobile apps, entirely on desk phones, or mix both. The right choice depends on how each person works.What internet do I need for VoIP?VoIP needs a stable connection more than a fast one. Each call uses roughly 100 kbps each way; low latency, low jitter and a wired network matter most.How many users or extensions do I need?A user is a person who signs in and makes calls; an extension is a dialable destination. Count people who need their own line, then add shared extensions.Can I test the system before my number moves?Yes. Your system is built on a temporary number so you can call in, try menus, ring groups and apps, and adjust the setup before your real number ports.
