Traditional SIP Trunking requires complex capacity planning and charges for what you might use at the highest possible peak in a 36 month contract. Elastic SIP Trunking requires no contracts and has no channel limits, meaning you just pay for what you actually use. Additional calls per second can be purchased as needed.

Local carriers only provide local numbers, requiring multiple time consuming carrier contracts to get global coverage. Twilio offers an inventory of tens of millions of numbers across 50 countries, available to provision instantly. Each number is tested for 60 days to avoid those that receive unwanted call traffic.

Voice connectivity is too important to rely on a single carrier or a single PoP. That's why Twilio provides the resilience of being connected with local carriers, out of local PoPs in 5 continents designed to eliminate single points of failure. Any call you make can be terminated through 4+ local carriers to withstand any number of component failures.
