8. What is SIP? Stands for “Session Initiation Protocol”. A set of rules that provides the basic signals used to initiate, manage and terminate communications.

9. What’s Different About SIP? Ability to CONVERGE real world communications infrastructure far beyond the ability of traditional PSTN (Public Switched Telephone Network). SIP and its supporting extensions and protocols is being designed as the industry standard session control protocol for setting-up and controlling all voice, video, broadband, mobile and multimedia communications; and enable internetworking between IP-based telecom networks and non-SIP telecom networks such as traditional telephony.

10. Real World Benefits of SIP VoIP mobility. Location independence instead of the traditional attachment to physical location of PSTN. Ease and speed of provisioning to end-users and disaster recovery security. Choice and cost. Simple IP connections with the public internet or private IP infrastructure gives the consumer greater options, less dependence on hardware and a greatly reduced price.

11. What is SIP Trunking? It’s a VoIP trunk that utilizes SIP for session control. Enables pure IP connection from the enterprise to the carrier and connection through the carrier’s PSTN gateway to the public network. The enterprise doesn’t need to maintain its own circuit-switched handoff to the PSTN.

12. SIP Trunking Benefits Only need to maintain one IP-based connection for both data and voice. Separate on-premise PSTN and data circuits no longer required. Fewer circuits, less interfaces, more efficiency, more cost effectiveness. Easier to maintain diverse and redundant IP-based connections to ensure superior reliability and security.

13. SIP Trunking Benefits No longer need to buy or maintain multiple PSTN connections and dedicated PSTN interface hardware. No longer need PRI connection. Increased enterprise productivity and applications efficiency.
