Make business calls from any phone — with your office caller ID.
Dial into your EMAK system from a personal phone, hotel phone, or any device, and place outbound calls that display your business number. DISA keeps your personal number private and your professional image consistent.
87% of people screen calls from unknown numbers. If you call a customer from your personal cell, they probably won't answer. DISA fixes this — your business caller ID, from any phone.
Included in every plan — from $20// extension / month.











Consistent caller ID. Private personal number.
Without DISA, calls from your personal phone show a personal number — and 87% of customers screen those. With DISA, every call from every phone shows your business caller ID. Your customers recognize you. Your personal number stays private.
PIN-protected per user for security. Direct inward system access means your business phone system travels with you — home, on the road, or at a client site.
Your office phone travels with you.
DISA covers the gaps the softphone doesn't — hotel rooms, borrowed phones, spotty Wi-Fi, locked-down client sites.
Traveling executives
Hotel phone or borrowed cell? Dial DISA, enter your PIN, then place the call as if you were at your desk.
On-site at a client
Locked-down guest Wi-Fi? No softphone? Use the client's lobby phone or your cell — DISA handles the rest.
Personal-number privacy
When you call a customer from your personal cell, your office number shows — not your private one. The line you actually share with family stays yours.

Frequently asked questions.
What is DISA in VoIP?
DISA (Direct Inward System Access) lets you dial into your VoIP phone system from an external phone and place outbound calls as if you were in the office. The recipient sees your business caller ID, not your personal number.
Can I make outbound calls with my business caller ID from my cell?
Yes. Dial your DISA access number from any phone, authenticate with your PIN, and place the call. The recipient sees your business number and name — exactly as if you called from your desk.
Is DISA secure?
Yes. Each user has a unique PIN, and EMAK supports IP restrictions and call destination limits to prevent unauthorized use. DISA access can be enabled or disabled per extension from the admin portal.
What is the difference between DISA and a softphone?
DISA lets you use any phone — hotel, payphone, borrowed cell — to make calls with your business caller ID. The softphone requires an internet connection but gives you the full phone experience from a browser or app. DISA is ideal when you don't have internet access; the softphone is ideal when you do.
Does DISA work internationally?
Yes. You can dial into your EMAK system from any phone worldwide and make outbound calls with your business caller ID. Standard long-distance rates apply for the inbound leg to your DISA number.
