The traditional Public Switched Telephone Network (PSTN) has served businesses for over a century. But copper infrastructure is aging, expensive to maintain, and increasingly being phased out worldwide. SIP trunking represents the modern alternative.
The Cost Comparison
A typical Jamaican business with 8 copper phone lines pays significantly more per month than the equivalent SIP trunk service. Factor in long-distance charges, maintenance fees, and the cost of adding new lines, and the savings become even more dramatic.
With SIP, you pay a flat monthly rate that includes unlimited inbound calls and predictable costs. No surprise charges for line maintenance or emergency repairs.
Scalability: Night and Day
Adding a copper line means scheduling a technician, running physical cable, and waiting days or weeks. Adding a SIP channel takes minutes and can be done from a web dashboard.
Reliability and Redundancy
Copper lines have a single point of failure — if the physical line is damaged, you lose service. SIP trunks can route calls through multiple internet paths, automatically failing over if one connection drops.
The Bottom Line
Every metric favors SIP: lower cost, faster scaling, better reliability, more features. The only question isn't whether to switch, but when.
