SIP Trunking Assessment Criteria

Many SMBs have accepted IP communication as a method for placing internal and external calls. They are now taking a closer look at SIP Trunking, the technology that numerous enterprises have already enthusiastically embraced. Migrating to a new technology involves risk and some SMBs are hesitant to take the step. Knowing where to begin is a challenge.

There are five assessment criteria for SMBs to consider when investigating the migration from TDM to VoIP to SIP Trunking. VARs need to familiarize themselves with the assessment areas and prepare appropriate responses. Properly responding to the assessment criteria will ameliorate the risks in favor of the benefits and potential.

Cost: The current economic environment creates an opportunity for SMBs to address cash flow and profit margins. SIP Trunking allows an SMB to implement converged services (voice, data, video), immediately eliminating the need for separate dedicated lines. Moreover, when SMBs deploy SIP Trunking with an IP PBX the resulting savings can easily increase their profit margin. Unlimited local and long distance calling over a converged connection (DSL, T1 or DS3) can drop monthly telecom costs from $2800 to $840, a 70% savings, because entry SIP Trunks average $11-13 per month per call session while POTs lines are usually twice that amount or more.

In addition to the cost of the service, the second major item of savings is the actual IP PBX. It can represent significant cost savings over a TDM platform. IP PBXs range from very simple PC servers running open source software to proprietary implementations, all at a much lower cost than their predecessors.

Quality of Service (QoS): A business needs its phones and they must work reliably with good voice quality. Historically, POTs lines have led the way and many SMBs were disappointed with the public Internet VoIP voice quality and service. Today, private IP networks are available, offering QoS and reliability equal to that delivered over a TDM network. SIP Trunking deployed on a private network, such as the robust nationwide network built and engineered by Broadvox, is proven to satisfy the most discriminating customers. Quality of service also requires a strong customer service capability, availability and trouble ticketing process. The correct network supplier will have all of these elements in place.

Solution Offering: What is the existing telecom equipment and what is proposed? VARs can assist SMBs in defining their unique communications requirements. SMBs may realize that their legacy equipment is feature rich, but lacking in ability to maximize use of the Internet or migrate to a converged infrastructure. SMBs need to compare the added value of new equipment versus adopting a hybrid solution using legacy CPE with SIP enabled IADs and gateways versus doing nothing. Properly defined solutions can be deployed with minimal disruption of daily business transactions and short training periods. Deployment can be staged or cutover all at once; the strategy should be identified within the solution proposal.

Support: Before deploying a SIP Trunking solution, SMBs must have the assurance that support will be available for the solution should a problem occur. With Broadvox, support is provided through an experienced customer service organization, strong team of SIP engineers able to address any interoperability or provisioning issues and a 24×7 Network Operations Center continuously monitoring all traffic and network conditions.

The VAR has support responsibility as well. The VAR must be ready to address equipment issues, configuration questions, router installs, etc. Support must be available as part of the proposal or on a pay per need basis. Understanding the commitment of both the VAR and service provider is a key criterion for the SMB, and should be spelled out in the proposal and service level agreement.

Standards Compliance: Most new telecom equipment is IP enabled and SMBs must search for solutions that will enable them to take advantage of the available productivity enhancements. Today, SIP enabled servers and services are not plug and play. Similar to the early days of T1s, SIP Trunks need to be tested between the OEM IP PBX, IAD or media gateway prior to being deployed in a customer environment. The testing should result in the equipment and service being certified by either the OEM or the service provider.

Interoperability that is certified has the highest potential to support the next generation of converged service applications such as unified communications, presence, find me/follow me, and many others. VARs again can step in to guide end users to the best solution to enable SMB infrastructures when implementing this new software.

In summary, SMBs must not stagnate during these economic times. VARs must assist them in quickly assessing the best strategy to move forward in implementing IP communications. The five key assessment criteria are cost, quality of service, solution offering, support and SIP standards compliance. Deployed properly, SIP Trunking will deliver the level of VoIP communications SMBs and enterprises require and want.

  1. SIP trunking is the way of the future no doubt. Why pay for a PRI when you can SIP trunk your traffic out over your existing internet connection? You can add channels on the fly. And this is at a fraction of the price. The most important thing though is the quality of the calls. Make sure you are running QOS as you stated in the article.

    If you do not have a SOLID internet connection with ample bandwidth SIP trunking should wait until you sure up your connection issues.

    The bottom line though is that it is a money saver!

  2. SIP Trunking is gaining in popularity for sure but the what you save in bandwidth per call compared to a PRI, you need to feed that savings back into qualified support to properly configure your equipment and manage network issues as they arise.

    A PRI is so easy to set-up and manage. You plug in and the little light goes from red to green and you are making calls. A SIP Trunk may involve setting up a SIP Proxy, Firewalls, QoS, IP-PBX, NAT rules et al; not so easy.

  3. ISG-Telecom is a CLEC regulatory (legal) consulting firm that was founded in 1996, and since then our staff has been creating CLEC strategies in an effort to maximize profits for new entrants. During that time frame ISG has helped hundreds of entrants become CLEC’s, Inter-Exchange Carriers and VoIP providers.

    Our legal staff combined with the retention of some of the best telecom attorney’s in the USA, when needed for certain jurisdictions, makes us the only choice for certifications with any PUC (Public Utility Commission) throughout the USA or the FCC (Federal Communications Commission). In 2008 we introduced international certifications for our clients wishing to do business in Canada, Mexico, Europe and the Eastern Block. Our focus has been the same for twenty + years – “Get our clients certified in the shortest period of time with the least amount of energy on their part”. We have a 100% track record for getting approvals and completing all certifications in record time.

  4. i would highly recommend Colynk if you’re looking for a voip provider. ive been a loyal customer for two years now and i couldnt be happier with colynk
