A ticket number is not an answer. When a business phone system fails, a support reply that arrives three days later might as well not arrive at all. Jill Muensterman, President of IParigon, built her company around that conviction. The woman-owned VoIP provider, headquartered in Evansville, Indiana, calls itself "the phone company you can actually get on the phone." To keep that promise to businesses across the Midwest, IParigon needed an upstream carrier that answered just as fast.
When IParigon launched, Muensterman knew exactly what she didn't want: rigid contracts, for her company or for her customers.
"We were looking for a provider that would be flexible on terms," she said. "Frankly, we didn't want to get locked into weird things, and we didn't want our customers to either. Our model is very flexible, and people love that they can just add or remove services at any time."
Pricing mattered too, but in those early days, responsive support mattered most.
"We needed somebody that was good with support, that actually responded quickly and didn't just give you a ticket number where three days later you finally get an answer to your question," said Muensterman. "These are phone calls. We need speed."
Telnyx delivered on both counts, and the contrast with other vendors became impossible to ignore. "We had a couple of other providers we were working with in the early days, but pretty quickly we were like, why don't they do things like Telnyx?" she said. "So we went pretty much all in with them as quickly as we could."
IParigon's first customer on Telnyx was no small test: a sizable healthcare facility, where a missed call can mean a missed appointment or worse. The engineering team blocked off an entire day to build the connection, provision DIDs, and coordinate the port on SIP trunking from Telnyx.
They didn't need it.
"They walked down the hall in a daze and said, we're done. That was it," Muensterman recalled. "You have to know what you're doing, but it was fairly intuitive. It works great!"
What began as straightforward SIP trunking has grown into a much deeper partnership. IParigon now relies on Telnyx to host its STIR/SHAKEN certificates, keeping outbound calls attested and trusted. As texting became a must-have for its clients, IParigon leaned on Telnyx to navigate 10DLC registration for SMS and MMS campaigns.
"We use them to help us get through that process," said Muensterman. "Today, we are working to integrate the AI Agents."
Demand for voice AI agents is coming from every corner of IParigon's customer base, from small insurance offices to car dealerships. "Everybody is much more interested in this as it becomes more commonplace," she said. "Heating and air places ask, how do we manage this huge volume of calls with our small staff, when we only need them at certain times? Telnyx has some pretty amazing products on that. We can't wait to get those deployed as well."
Serving healthcare practices, manufacturers, and government offices across Indiana, Kentucky, and beyond, IParigon stakes its reputation on call quality. Muensterman has a favorite way of testing the competition: answering their sales calls.
"Funny enough, I get calls from competitors saying, hey, try our stuff, and I'm like, do you realize there's an echo when you call me? Do you realize your call quality is terrible? Why would I use you?" she said. "It's reliable, and the calls sound great. Telnyx has really never given us a reason to shop around."
Beyond the reliability and competitive pricing, what keeps Muensterman confident is the pace of the platform itself.
"They're constantly adding capabilities. There are so many things on that website where I think, I don't even know how or when I would use that, but wow, there's just constant development," she said. "You don't feel like, well, we're really good at this, but when we need to do that, we're going to be stuck. They're very forward-thinking."
For a company built on picking up the phone, that combination of carrier-grade quality and human responsiveness is the whole point. IParigon promises its customers a phone company they can actually reach. Telnyx makes it a promise Muensterman never has to hedge.
