Is SIP Trunk Reliability Holding Back Businesses From Adopting SIP?

Methods to improve SIP trunk reliabilityCrossing the Chasm: Looking at SIP Adoption in 2017

SIP trunking provides the foundation for unified communications and other advanced communication services – things like video and web conferencing, voice over IP, contact center applications, soft client-based communications, and other applications are all facilitated by SIP trunking.

Businesses seem to be getting that, based on recent data. Industry firm Infonetics predicts hat SIP adoption rates will increase to 62% or greater in 2017. According to their report, SIP adoption rates are increasing dramatically, and the unified communications market is expected to reach annual revenues of $88 billion by 2018.

And yet, some enterprises hesitate to move to SIP.  The reason for this appears to be twofold – on one hand, enterprises are either currently in the middle of a contract for telecommunication services that for whatever reason makes it difficult to switch to SIP trunking; on the other hand, some businesses are afraid to make the move, for fear of disrupting their communications if the cutover goes poorly, or issues like SIP trunk reliability.

Why Choose SIP Trunking?

So, if cutting over from T1 trunking or some other traditional communications standard poses any risk at all to the enterprise, why make the move? What benefits does SIP trunking provide to those who plan to make the move in the near future? And, more to the point, what’s in it for you? SIP trunking provides:

  • Communication functionality and capabilities that aren’t dependent on the underlying access and transport.
  • Services that can run across diverse platforms and devices.
  • Open,  standards-based architecture that integrates across vendors (i.e., no vendor lock-in).
  • Flexible communications and collaboration environments.
  • Integration with open and higher-level applications and application standards like XML, VXML and Java.

SIP and VoIP:  The Killer App

But are those benefits enough? For some companies, the capabilities provided by SIP trunking are meaningful enough to justify the move. But for other companies, they want to see more, especially in the areas of cost savings. And that’s a fair point.

Enter Voice over IP (VoIP), the implementation of which is the most basic, fundamental benefit from SIP trunking. By implementing VoIP with SIP trunks, enterprises and small businesses alike can realize costs savings in areas like:

  • Convergence  – by combining voice, video and data into a single access type, businesses typically save significant costs over non-converged approaches
  • Voice cost savings – SIP trunks typically can carry much more voice traffic and maintain more concurrent calls than T1 or PRI trunks, making the SIP connection more economical
  • Free on-net calling – SIP trunking typically means free site-to-site calling between locations on the same SIP network, meaning that inter-office communications are much cheaper than traditional networks.

There are more cost-saving benefits to be had, from areas like network management and local and long-distance dialing plans, but even just the three points above illustrate the potential for significant cost savings through the use of SIP and VoIP.

Why Do Businesses Hesitate?

Regardless of the benefits, there are still challenges in moving to SIP trunking. One of the primary challenges is actually an old problem – finding the right provider to trust with your communications and addressing things like SIP trunk reliability.

SIP adoption is really like adopting any other technology – it provides a range of benefits like those identified above, but it introduces risk while the new technology is implemented and made operationally viable.

That’s why it’s important to work with a provider who specializes in this space. There are also some key considerations to take into account, which we cover in this post.
