Do I need a separate phone number for each teammate, client or campaign?

Your account needs at least one phone number, because an outbound call has to come from some caller ID. Your whole team can share the same number. You can give each salesperson their own number if you want, but you do not need to.

If you are an agency, we recommend at least one phone number per client. For the same client and the same business or niche, you can run everything on one number: calls, SMS and all of that client's marketing campaigns.
