The global VoIP market will climb to $82.5 billion by 2019
Earlier this month, Infonetics reported that the global VoIP market rose to nearly $70 billion in 2014 and project that figure to climb to $82.5 billion by 2019 fueled by the continued adoption of business VoIP services by both enterprise and SMBs. The driver within the VoIP business services category: SIP trunking. These companies are replacing older PBX systems and an expensive analog telephony services delivered over the PSTN with lower cost SIP-based IP PBX or a unified communications (UC) solutions in combination with SIP trunking service.
The important building block, whether it an IP PBX or UC service, is the session initiation protocol (SIP), which is used to initiate and manage voice over IP (VoIP) communications sessions for these basic telephone services and for additional real-time communication services, such as instant messaging, conferencing, presence detection and multimedia video conferencing that are part of a UC service.
When planning a Skype for Business or Microsoft Lync deployment, it is important to understand this SIP connectivity. SIP trunking is VoIP and streaming media service based on SIP offered by a service provider (ITSPs, SIP trunking providers etc.) that delivers telephone services and unified communications for a business using a managed cloud-based VoIP solution or a premise-based IP-PBX or UC platform.
Here is how Microsoft Technet defines SIP trunking: “A direct connection between your organization and an ITSP.” It enables you to:
- Extend VoIP telephony beyond your organization’s firewall without the need for an IP-PSTN gateway;
- Carry instant messages, multimedia conferences, user presence info, enhanced 9-1-1 (E9-1-1) emergency calls, and other SIP-based real-time services;
Because it’s easier to configure and less expensive to design, operate, maintain, and upgrade, and because ITSPs deliver services at substantial savings, your investment in SIP trunking can give a quick and substantial return on investment.
The key advantages of SIP trunking are cost savings, operational flexibility and simplicity for business telecommunications. SIP trunks integrate data, voice and video in a single line, eliminating the need for separate physical media for each mode. SIP trunking allows large enterprises with multiple sites to consolidate connections to the public switched telephone network (PSTN) at one centralized location. Previously, companies would usually use time division multiplexing (TDM) trunking, which requires a separate trunk from each branch site.
