How can multiple employees use one business phone number?
A shared business number is how small teams look professional without buying a phone per person. Atly puts one company number (and its channels) in a shared workspace: calls, SMS, WhatsApp and email land in one place; outbound drafts wait for human approval.
What “shared” means in Atly
- One company number SKU (up to 10 E.164 numbers per company where policy allows)
- Team inbox for inbound voice, SMS and WhatsApp on that number
- Roles so owners/admins connect numbers and members work the queue
- HITL outbound — AI drafts; people approve before customers get SMS, WhatsApp or email
It is not a classic call-center ACD with wallboards, and not a personal SIM shared by password.
Voice, SMS and WhatsApp on the same line?
Only when the purchased SKU supports each channel. The setup wizard and Provider Engine reflect live catalog capabilities. See [voice, SMS and WhatsApp](/voice-sms-whatsapp) and [WhatsApp on a business number](/whatsapp-business-number).
Existing number or new Atly number
Teams can forward or keep an existing business line where supported, or buy a new Atly number. Porting is documented separately: [phone number porting](/phone-number-porting).
When a call center fits better
If you need dense agent seating, call recording analytics and queue KPIs as the product, a specialist call-center tool may fit better. Atly is business communication infrastructure — number + channels + approved work — not a traditional call center.
