Why businesses pick DataTel 360 for SIP trunking
Works with the system you have
SIP trunking connects your existing phone system to modern carrier voice. Keep legacy PBX running, or plan a clean move to hosted voice later.
Trunks sized to real call volume
We size trunk capacity to the calls you actually make, so you are not paying for paths you never use.
Secure signaling and failover
We configure secure SIP signaling and encryption, plus failover routing so calls keep flowing when a primary circuit fails.
One contractor for voice and cabling
Same team handles cabling, network, WiFi and phones. That means one accountable partner instead of finger pointing between vendors.
24/7/365 support with live dispatch
Phones down is an emergency. Our average response time on critical outages is under 15 minutes.
Single site or many sites
We cover metro Atlanta, Georgia and the Southeast, with nationwide field dispatch through our TechDispatch360 division.
What your SIP trunking project includes
SIP trunking replaces older voice circuits with carrier voice service delivered over your data connection. We start by looking at how many calls your team really makes at once, what equipment you have, and how calls need to route. Then we build the trunks around that.
We are carrier neutral. We do not own a network, so we source the service that fits your business and configure it properly on your phone system.
- Trunk capacity sized to your actual concurrent call volume
- Number porting managed end to end so you keep your business numbers
- Dial plan, call routing and auto attendant setup
- Secure SIP signaling and encryption
- Failover routing so calls continue when a primary circuit drops
- Works with legacy PBX, hybrid setups and hosted platforms including Zultys and Intermedia Unite
- Voicemail-to-email, call queues and mobile softphone extensions available
- Cutovers scheduled so users move without downtime
Serving Atlanta businesses since 1998
“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).”
“Our company has one Corporate and 12 branch offices. The MX250 VoIP server we purchased from Datatel360 in 2012 has proven to be an asset to our offices. We have some fairly unique needs and requirements which Michael has continued to help with being a liaison with Zultys to get us answers and support. Even though VoIP is more complex than our old PBX systems, we have had a substantial cost savings allowing us to remove 5-6 AT&T POTS lines per site.”
“DataTel 360 has been our technology partner for business phone equipment, solutions and professional services for the past 6 plus years. Michael and Marsie have been extremely helpful to our organization in terms of assisting us in times of need and expediting solutions that meet our ever changing needs. When called upon, they have been helpful to just give advice which is invaluable when trying to determine what we want to do as a company since we are growing. As technology changes so quickly, they are there to advise and give open and honest opinions about what options are available. They consistently go above and beyond to help us and make sure we get shipments very quickly when new equipment is needed due to additional staff members coming on board or need a new gadget. We here at Berkshire Hathaway HomeServices Taliesyn Realty appreciate doing business with the DataTel 360 team and we continue to turn to them for training, advice, and additional needs as it relates to our voice communications systems. Their team works hard and long hours if needed to make things happen and they are always pleasant to deal with each and every time they are called upon for assistance. Even though they are a distance away from our offices, we feel like they are right next door when we need them. I highly recommend DataTel 360 for your phone and telecommunications systems whether it be cloud-based or onsite.”

Frequently asked questions
How much does business SIP trunking cost?
Pricing depends on how many concurrent call paths you need, how many phone numbers you port, how many sites are involved and what equipment you already have. We are carrier neutral, so we price options and show you the fit before you commit. Ask for a quote and we will scope it.
Can we keep our current phone system?
Yes. SIP trunking connects your existing phone system to carrier voice service. We support legacy PBX, hybrid setups and hosted platforms such as Zultys and Intermedia Unite, so you do not have to replace working equipment to modernize your lines.
Will we keep our existing phone numbers?
We manage number porting as part of the project, along with dial plans, call routing and auto attendant setup, and we schedule the cutover so your team moves over without downtime.
What happens if our internet circuit goes down?
We build failover routing into the trunk configuration, and we can add internet failover with cellular backup so phones and payment systems stay online. If something breaks, we run 24/7/365 emergency support with live dispatch.
Do you support multiple locations?
Yes. We serve metro Atlanta, Georgia and the Southeast directly, and we cover multi-site and out-of-state locations nationwide through our TechDispatch360 dispatch division.
Do you work with residential customers?
No. DataTel 360 works with businesses and organizations only, including healthcare, legal, manufacturing, logistics, retail, hospitality, government and education. We do not sell home phone or consumer service.
