SIP Trunking Offers a Host of Advantages to the Enterprise


September 09, 2016

There are a lot of misconceptions about making the switch from legacy PSTN-based phone systems to IP and cloud-based offerings. Change is scary for any business, and taking the plunge into the world of IP-enabled PBX and session initiation protocol (SIP) trunking can be confusing for even the most informed decision maker.

Fusion, a company that offers the FusionSIP solution for connecting IP-enabled PBXs to the PSTN via broadband, recently set out to dispel some of the myths surrounding SIP trunking technology. One of the most common misconceptions about making the shift to IP and the cloud using SIP trunking is that it’s prohibitively expensive. This is simply not the case, and SIP trunking can slash monthly telecom expenses in half, according to Fusion.

Another popular theory about SIP trunking is that it creates security risks and vulnerabilities. But solutions like FusionSIP route calls through a multi-functional router that also acts as a firewall and a line of defense against fraud. Many decision makers also wrongly conclude they will need to replace all of their existing equipment if they make the move to an IP-based solution, when in reality, many SIP trunking services are interoperable with a variety of devices. Offerings like FusionSIP also include DNS-based SIP trunk registration, ensuring redundancy in the event of a network failure.

With some of the more common myths associated with SIP trunking dispelled, we can now discuss it’s myriad advantages. Fusion purports that enterprise SIP trunking can reduce average telephony costs by up to 33 percent, largely because IT departments are no longer tasked with supporting and managing outdated and cumbersome legacy equipment.

SIP trunking also reduces actual calling costs since companies are dealing with one service provider instead of a variety of legacy carriers. That simplifies billing and accounting and enables business processes and operations to be synchronized across the board. The costs associated with infrastructure expansion and growth are also decreased when using SIP trunking since new lines may be added without the need for additional hardware.

Another massive benefit of SIP trunking services is that voice and data traffic is merged on a single network, enabling better use and management of available bandwidth. Redundancy is also improved, since service providers handle outages and issues and internal IT resources are not required. This also promotes business continuity and offers more options for backup and disaster recovery planning.

The idea of moving to an IP-based communications solution may seem daunting from a planning and management perspective. But SIP trunking is a viable and attractive alternative to outdated legacy connectivity and its associated hardware and headaches.
