Telecom shouldn't be a black box.
We spent years dealing with legacy carriers, unpredictable per- minute billing, and degraded SIP quality. We built UnlimCall to give outbound teams the infrastructure they actually deserve.
The telecom industry is broken. For decades, legacy carriers built obfuscated routing tables, hidden surcharges, and per- minute billing models that punish growth. As your sales team scales, your bill scales with it — non-linearly.
We looked at the market and saw modern SaaS companies operating at lightning speed, while their underlying communication infrastructure was stuck in the 2000s. We decided to fix it.
UnlimCall was founded on a simple premise: abstract the complexity. We handle the carrier negotiations, the localized SIP infrastructure, and the STIR/SHAKEN compliance. You pay a predictable flat rate per seat and start dialing.
The rules we build by.
We are SIP engineers, distributed-systems architects, and telecom veterans. Four constraints we hold the network to.
Telecom should feel like software
Provisioning a global SIP trunk or rotating a flagged Caller ID should be an API call, not a 3-week email thread with an account manager.
Predictability over pennies
We reject the per-minute race to the bottom. We optimize for routing quality and flat-rate predictability so CFOs do not audit telecom invoices.
Latency kills sales calls
We deploy SIP edge locations as close to your floor as possible — sub-50 ms one-way audio in covered geographies, regardless of where your agents sit.
Custom routing engine
Not an off-the-shelf PBX. A distributed routing engine designed to handle thousands of concurrent sessions without dropping packets.
