SIP

What is SIP?

Session Initiation Protocol (SIP) is a protocol for setting up and terminating multimedia communications. Protocols are the “rules” that devices or computers use to exchange data. 

These devices, better known as endpoints, can communicate as long as they agree to use SIP. Even endpoints from different vendors can work together using this protocol, making it the industry standard for many businesses. 

SIP is currently under the control and management of the Internet Engineering Task Force (IETF), which developed and standardized the protocol. 

What are the benefits of SIP? 

The appeal of SIP lies in its flexibility. It not only involves the messages traveling between endpoints in a network but also the exact rules on how to set up sessions. SIP powers various types of communication, including phone calls, VoIP, instant messaging, video conferencing, email, and media sharing. 

Some of SIPs benefits include: 

  • Improved audio quality: Sound quality is noticeably better over VoIP than through traditional telephone lines. Better audio makes for a less frustrating and more pleasant experience. 
  • Enhanced scalability: There’s no need for complicated configurations or expensive hardware installations. SIP allows you to upgrade your communication system efficiently. 
  • Cost-effectiveness: Traditional phone lines can be expensive to maintain, but SIP phones are less complex. Softphones even negate the need for additional hardware. 
  • Employee mobility: Under SIP, everybody can work together. Remote workers won’t feel left out since you don’t have to be at your desk to use it. 
  • Cybersecurity: Some businesses considering Internet communication are concerned about security. Reputable SIP phone vendors provide encryption, which protects your data as it travels through the network. 
  • Integration support: SIP phones can work closely with your customer relationship management (CRM) tools and other business applications for even more added functionality. 

Companies can even manage a SIP phone system directly from the cloud, enabling them to pick up new features and scale up network capabilities as needed.
