Frequently asked questions.
What is a phone extension?
A phone extension is a short internal number (like 101, 102, 103) assigned to a specific person or department within your business phone system. Callers can dial extensions directly, or your virtual receptionist can route them. Each extension has its own voicemail, caller ID, and forwarding settings.
How many extensions does a small business need?
A good rule of thumb is one extension per team member, plus shared extensions for departments (sales, support, billing). Most small businesses on EMAK's VoIP system start with 5-15 extensions and add more as they grow — there's no limit, and adding a new extension takes about 60 seconds.
Can I add extensions without buying new phones?
Yes. Every EMAK extension works with the browser-based softphone app — no physical phone required. New team members can start making and receiving business calls from their laptop on day one. Add a desk phone later if you want, or keep using the softphone permanently.
How many extensions can I have?
There is no limit. Add extensions as your team grows — each one includes all 40+ features. Whether you have 5 employees or 500, your phone system scales with you.
Does each extension cost extra?
Each extension is priced per the plan tier. Every extension includes all features — no add-ons required. You never pay separately for voicemail, caller ID, forwarding, or any other capability.
