Why Businesses Choose SIP Trunking for IP-PBX

SIP trunking has garnered impressive market share and continues to gain in popularity among small and large businesses. As companies move from older telephony systems

in the world of unified communications (UC).

SIP trunking has emerged so quickly that many professionals need it without realizing they need it. Let’s explain what SIP trunking is, why it’s integral to modern business, and how it’s being implemented.

SIP Trunking in Plain EnglishEvery communications system needs a protocol for handling calls, video conferences, messaging, and other sessions. SIP, which means session initiation protocol, is the standardized architecture for starting and stopping phone sessions on IP-based systems.

What is SIP trunking? Whereas SIP is the architecture, SIP trunking refers to the service. Like a tree trunk with branches, SIP trunks provide bundles of lines that can be used for calls and other sessions.

Those familiar with PRI or T1 trunking are accustomed to expensive trunks of 24 lines each. SIP trunks do the same work while also powering more than just calls — audio, video, file transfers, and etc.

SMBs and the Meteoric Rise of SIP TrunkingBusinesses overwhelmingly have flocked to SIP trunking when adding or updating communications systems. More than 20 percent of active business trunks were SIP-based as of 2014; that market is growing annually and is expected to become an $8 billion market by 2018.

From cost-cutting to future-proofing, it’s easy to see why SMBs are jumping on SIP to power their next communications solution:

• Cost savings of 30 to 60 percent can often be achieved by switching from PRI or other older systems.• Equipment can be legacy hardware or software-based phones. If desired, any desktop computer can function as the

hardware. Businesses only need to buy new equipment if the latest IP business phones are preferred.• Sizing and scaling of voice plans becomes easier. SIP trunks are small and inexpensive, powering two to four channels.
