Key Terms

sip trunks, least cost routing, quality of service

3 terms

sip trunks technical

"including unified communications, private 4G/5G, contact center, or SIP trunks."

A SIP trunk is a virtual phone connection that uses internet protocols to carry voice and other real-time communications between a business and the public phone network, replacing traditional physical phone lines. Think of it like switching from mailed letters to email for phone calls: it bundles many call channels over a single internet link, affecting a company’s communication costs, scalability, redundancy, and how easily it adds or moves phone capacity.

least cost routing technical

"address least cost routing (LCR), quality of service (QoS) routing, toll-free"

Least cost routing is a system that automatically chooses the cheapest available path to carry a call, data session, or payment by comparing multiple networks, carriers or clearing routes in real time while still meeting quality needs. Investors care because it lowers a company's ongoing service costs and can boost profit margins and cash flow without raising prices, similar to a driver picking the cheapest gas station that’s still convenient and reliable.

quality of service technical

"least cost routing (LCR), quality of service (QoS) routing, toll-free"

A measure of how well a company delivers its services to customers, usually judged by reliability, speed, accuracy, uptime, and response or resolution times. Like judging a restaurant by the food, speed, and friendliness of staff, it signals whether customers get what they expect and how often problems occur. Quality of service matters to investors because it influences revenue, customer retention, operating costs, regulatory compliance, and a company’s reputation.
