The Old Way vs. The Interlink Way
Most multi-location businesses are running fragmented systems that cost more, break more, and take more IT time to manage.
Fragmented Systems
Hidden costs add up fast
Interlink Unified
Predictable, consolidated billing
Professional call routing across every location.
Your callers always reach the right person, at the right location, at any time of day — without a receptionist manually transferring calls. Multi-level auto attendants can be configured per office, per department, or per time schedule.
Per-location greetings
Each office gets its own branded greeting and menu.
24/7 intelligent routing
After-hours menus, holiday schedules, and overflow routing handled automatically.
Cross-location transfers
Transfer a caller from your LA office to your Denver branch in one touch.

AvailableJust dial the extension. Every user at every location, reachable in seconds.
Reach anyone, anywhere, with a 3-digit extension.
One unified dial plan covers every employee at every location. No one needs to know a colleague's cell number or look up a branch's main line. Just dial the extension — whether they're across the room or across the country.
Shared dial plan
Extensions work the same whether you're in the office, at home, or on mobile.
Presence visibility
See who's available, on a call, or away before you dial — saving time for everyone.
Interoffice transfers
Transfer calls between locations like they're on the same floor.
Every communication channel. One platform.
Stop paying five vendors for five tools. Interlink's UCaaS platform consolidates every communication channel your business uses into a single app your team already knows how to use.

App for your team
Web, desktop, and mobile
No hardware. No server room. No headaches.
Traditional phone systems require a PBX at every office — hardware that needs to be purchased, racked, configured, maintained, and eventually replaced. With Interlink, every location runs on our cloud. Adding a new site takes days, not months.
Zero capital expense
No PBX hardware to buy. No installation fees. Start with a monthly subscription.
New locations in days
Adding a new office is as simple as provisioning extensions in our portal and shipping phones.
Fully managed by Interlink
We handle every firmware update, security patch, and configuration change — you focus on your business.
Scales instantly
Add or remove users at any location at any time without buying new hardware or reconfiguring systems.

REMOTE USER EXPERIENCE

Desk Phone

Same extension. Same features. Same call quality. Whether your employee is in LA or on the road in Austin.
Your remote team is your office team.
Remote employees get the exact same phone system features as in-office staff — the same extension, the same call quality, and the same presence in your company directory. No separate licensing, no workarounds, no compromises.
Any device, any location
Laptop, mobile, browser, or desk phone — all supported out of the box.
Appears in the company directory
Remote users are fully visible to the rest of the team, with presence status.
Transfers and conferencing
Remote staff can transfer, conference, and park calls just like they're in the building.
No VPN required
Our cloud-hosted SBC handles all the heavy lifting — remote users just need internet.
Internet goes down. Your phones don't.
Each Interlink location is protected by a Session Border Controller (SBC) that keeps internal calls and essential functions running even when the internet connection drops — a critical safeguard for multi-location businesses.
Internal calls stay up
Employees at the affected office can still call each other during an outage.
Automatically recovers
When connectivity is restored, the system reconnects and syncs without any manual steps.
Per-location resilience
One site going offline doesn't cascade to other offices — each site operates independently.
