Oklahoma-Based · Zero Contracts · One Person Who Actually Answers
Cool Telecom — Fully Dialed In
Business phone service for absolutely anyone — solo operators, growing offices, law firms, nonprofits, whoever — built by someone who's tired of watching small businesses get treated like a number.
No Contracts. No Surprises. No Hassles. No Kidding.
Cancel whenever you want, for any reason. We just don't think we'll give you one.
Built for Literally Anyone With a Phone
Cool Telecom is an Oklahoma-based VoIP business telephone company. We work with law firms, medical offices, nonprofits, retail shops, one-person home offices, and everything in between — if you make or take calls, we've already got a plan that fits.
Here's what makes us different: the person who quotes your service, configures your phones, and answers when something breaks is the same person — every time, for as long as you're a customer. Cool Telecom isn't a call center with a friendly name. It's Mark Mumma, backed by a chain of upstream carrier partners who keep the actual wires, towers, and switches running. Mark owns the relationship and the support. They own the infrastructure underneath it. You get one number to call, and someone who already knows your setup picks up.
Everything That Makes Us Cool
All the features the big carriers upsell you on — standard, not extra.
Cloud & Hosted PBX
Skip the equipment closet. Enterprise-grade phone systems, hosted and maintained for you.
Guaranteed Contacts™ App
Dial out from your cell phone and your business Caller ID follows you — guaranteed.
Caller ID & CNAM Protection
We actively manage your Caller ID so you don't show up as "Scam Likely" on your own customers' phones.
Auto Attendant & Smart Routing
Menus, schedules, and routing rules that actually send calls where they need to go.
Cell Phone Bridge & Remote Extensions

Call Recording & Records Portal
Every call logged, searchable, and playable — built for training, disputes, and compliance.
Robocall & Spam Blocking
Blacklist tools and active filtering keep the junk off your lines.
Advertising & Music On Hold
Turn hold time into ad time, or just play something that won't make people hang up.
Professional Voice Prompts
Allison Inside™ puts a polished, professional voice on every prompt — standard.
LandLine IM™
Business messaging that comes standard with every calling plan.
Fax, Reinvented
Yes, people still need fax. vFax makes it not painful.
Filevine Integration
Purpose-built integration for Oklahoma City law firms running Filevine.
Round-the-Clock Monitoring
Your system is watched continuously — closely enough to catch problems that aren't even ours to fix.
We caught it before they did.
One customer's phones went offline — not because of anything on our end, but because their office internet dropped. We noticed, called them, and had them back up with a router reboot before they even realized there was a problem. That's the "watching your back" you get by default, on every account.
The 30-Day Wow Guarantee
Try Cool Telecom for a month. Don't love it? Full refund of your service — no questions, no contract, no hassle. (There was never a contract to get out of in the first place.)
Service fee refunded regardless of condition. Phone hardware refunds require equipment returned in like-new condition.
