Why businesses hand the install to us
Certified on the platforms we install
We hold certified Zultys design, configuration and lifecycle support, plus Intermedia Solutions Expertise. The people who design your system also program and support it.
Phones and cabling from one contractor
If your building needs new drops, patch panels or an MDF cleanup, we do that too. No finger pointing between a cabling crew and a phone vendor.
Cutover planned around your workday
We port numbers, build call flows and provision handsets in advance, then schedule the switch so your team moves to the new system without downtime.
Vendor neutral advice
We are carrier neutral and work across major platforms, so we recommend the system that fits how you actually take calls, not the one tied to one brand.
Support that answers after hours
24/7/365 emergency response with live dispatch. Average response on critical outages is under 15 minutes.
One office or fifty
Multi-site rollouts across the Southeast and nationwide field dispatch through our TechDispatch360 division.
What a business phone system installation includes
We start with a site survey. We look at your internet, your cabling, your current phone equipment and how calls move through your business. Then we design the system and put the scope in writing before anyone pulls a cable.
Installation covers the handsets on desks, the software on phones and laptops, the call routing behind it, and the training so your staff know how to use it on day one.
- Cloud VoIP, hosted PBX and UCaaS on Intermedia Unite and Zultys Cloud
- SIP trunking with dial plans, call routing and SIP security
- Auto attendant, call queues, voicemail-to-email and number porting
- Desk phone provisioning plus mobile and desktop softphones for remote staff
- Legacy PBX support, upgrades and hybrid VoIP migrations
- Cat5e, Cat6 and Cat6A cabling, patch panels and MDF or IDF work when new drops are needed
- AI receptionist, call recording, transcription and call analytics on Zultys

“I had a great experience working with DataTel 360. They helped get our phone system up and running in a short time and had everything set just right for us. Great experience from the first call. I highly recommend them!”
“Exceptional Service and Support from Datatel 360!<br><br>We had Datatel 360 install a cloud-based phone system for our office, and the entire experience has been wonderful from start to finish. The technology itself is modern, reliable, and has streamlined our communication significantly—but what really sets Datatel 360 apart is their exceptional team!<br><br>Michael and Marsie were an absolute pleasure to work with. Michael was knowledgeable, patient, and made sure every technical detail was handled with care. Marsie brought a level of organization and responsiveness that made the whole process smooth and stress-free. Together, they made the transition seamless and ensured we felt supported every step of the way.<br><br>If you're looking for a professional, responsive, and genuinely helpful team to set up your office phone system, I can't recommend Datatel 360 enough!”
“I have been dealing with telecom vendors for over 30 years and Data Tel is the best yet and I know will be the last. We love the Zultys system and the support we get from Michael and Marsie. Finally found a vendor who can manage all our needs. (phones, voice and data).”

Frequently asked questions
How much does a business phone system installation cost?
It depends on how many users and sites you have, the platform you choose, the handsets you want, and whether your building needs new cabling. We survey the site first and give you a written quote before any work starts.
Can we keep our existing phone numbers?
Yes. Number porting is part of the cutover. We also set up auto attendants, call queues and voicemail-to-email so the new system matches how you handle calls today.
Do we have to replace our current phone system?
Not always. We support legacy PBX systems, handle programming and moves, adds and changes, and can run a hybrid migration so you move to hosted voice over time instead of all at once.
Do you install the cabling as well?
Yes. We install certified Cat5e, Cat6 and Cat6A cabling, patch panels, and MDF or IDF buildouts, then test, label and document every run. One contractor covers phones and cabling.
Which areas do you cover?
Metro Atlanta and Georgia, including Alpharetta, Roswell, Sandy Springs, Marietta, Duluth, Norcross, Lawrenceville and Kennesaw, plus the Southeast. Multi-site rollouts are covered nationwide through TechDispatch360.
What support do we get after the install?
Ongoing support from the same team, including moves, adds and changes. Emergency response is available 24/7/365 with live dispatch, and average response on critical outages is under 15 minutes.
