Everything you need to know about Global SIP Trunking
SIP Trunking is one way to place voice calls and send digital communications over the internet.
SIP trunking services allow us to make Voice over Internet Protocol (VoIP) calls, send SMS/MMS messages, place 911/emergency calls, and use other SIP-based real-time communications.
Speed, agility, and leanness are guiding principles for companies that need to stay competitive today. To support those principles, businesses need technology that supports them. The benefits of SIP trunking include:
The primary benefits of SIP trunks compared to Primary Rate Interface (PRI) are cost savings, cloud flexibility, and scale. Because SIP trunks are elastic, businesses can scale SIP services up and down to meet demand easily.
In addition, cloud-based voice like SIP removes the need for fixed overhead costs and on-premise equipment. The infrastructure costs for SIP trunking are also lower because SIP eliminates the need for primary rate interfaces (PRIs), which require enterprises to buy lines in bundles of 23. PRI customers who need 10 lines have to buy a bundle of 23, leaving 13 unused. SIP, however, can be purchased in whatever number of units a business requires.
SIP trunking allows businesses to converge networks because it’s an application, not a service. Just as copper lines transmit signals instead of creating them, SIP allows any endpoint to communicate with another, as long as the two endpoints both agree to use SIP. That means a single-location company can converge its networks, roles, and equipment into one system that meets all of its communication needs.
With all the advantages that SIP trunking offers, why do any companies still use traditional services? It’s simple. Traditional telecom has been in existence for over 100 years. Over its lifetime, copper has been widely adopted, of course, and it’s the telephone technology that most of us grew up using. The short answer is: it was the best option that businesses have had until recent years. SIP trunking is only about 10 years old. That means it was purpose-built to work in today’s business environment.
Since the advent of SIP trunking as a business tool, nearly 70% of decision-makers have adopted SIP, and of those adopters, 96% report satisfaction with call quality. A protocol can only achieve widespread adoption when it’s based on consistent standards. The guidelines for how a SIP trunk should work and interoperate with a phone system are defined and guided by the SIP Forum, an organization of telecom experts who work toward the continual improvement of SIP standards.
