On-Premise VoIP Phone System Connected to VoIP “SIP Trunks” through NEC’s Cloud EXPLAINED

This second podcast Bruce Gibbs, President of ServiceMark, covers the details of the VoIP configuration for an
On-Premise VoIP Phone System Connected to VoIP “SIP Trunks” through NEC’s Cloud.  

Traditional landlines utilizing copper cabling are quickly becoming a thing of the past. Businesses who are contemplating a telephone system and/or phone service change should avoid traditional phone service over copper cables as it has become obsolete for several reasons, including cost. Current cutting-edge phone system solutions and service are the way to go. These cutting-edge solutions almost always involve Voice Over IP (VoIP) technology.

So, the question is no longer “is VoIP right for my business?”. The question is instead “what configuration of VoIP is most cost effective and the best fit for my business?”.

Due to the reliability of some internet connections, it is now commonplace for ServiceMark to install an On-Premise VoIP Phone System that is connected to VoIP “SIP Trunks”.  With this configuration, illustrated in the diagram, there is no traditional phone company that is a part of the phone system and service solution.  The diagram in the podcast illustrates the public internet as the means of connectivity to “SIP Trunks” provided by NEC Cloud Services.  The phone system features and programming reside in the NEC VoIP Business Telephone System that is located on the customer’s premises (commonly referred to as an on-premise VoIP phone system) as illustrated in the darker shaded area in the diagram above.

For a successful deployment, it’s important to address points of failure that can cause poor phone quality and internet security breaches:

  • The company’s data switch(es) should provide Power over Ethernet (PoE) and Quality of Service (QoS) to insure quality phone calls.
  • The company’s router/firewall is also important regarding the quality of phone calls and for protection to guard against data security breaches which have substantially increased in recent years.
  • The internet connection itself is also a potential weak link or point of failure because not all internet connections are equally reliable to facilitate quality phone calls.  ServiceMark Telecom goes way beyond conducting a simple internet speed and ping test which only measures the quality during a snapshot in time.  ServiceMark installs a diagnostic tool that simulates over 1,000 phone calls through NEC’s Cloud Services during a minimum one-week test.  If there was any degradation of any of the over 1,000 simultaneous phone calls, ServiceMark will address the problem before the implementation of a cloud-based VoIP solution.  This has resulted in “0” intermitted call quality problems with any of our customers that utilize SIP trunks over a public internet connection!

An On-Premise VoIP Phone System Connected to VoIP “SIP Trunks” through NEC’s Cloud has proven to be the best fit for the following types of ServiceMark customers:

  • Customers with more than 5 phones.
  • Customers that have more telephone handsets than the need for simultaneous phone calls.  (i.e. at any given time, there are 6 people on the phone, but the customer has 15 handsets.).
  • Customers looking for the most cost-effective solution and wish to save money on a monthly basis.

In order to determine which VoIP solution is the “best fit” and most cost effective for a business, ServiceMark has developed a Total Cost of Ownership tool, which compares multiple solutions, and calculates the total cost of ownership over 3, 5, 7, and 10 years. It’s common to compare a Cloud (Hosted) VoIP Phone System Solution to an On-Premise VoIP Phone System Solution Connected to VoIP “SIP Trunks”.

Businesses can call ServiceMark at 816-478-2000 or request a no-cost business phone system consultation by submitting the form on the right.

We take the time to educate business owners on multiple business phone system solution options, helping them determine, through the total cost of phone system ownership calculations, which option is most cost effective and the best fit for their business, employees and customers.


ServiceMark Telecom make it easy for business owners to stay equipped with the latest business telephone system technology with easy and flexible financing options through Mid Continent Capital, a local company in the Kansas City area that has provided convenient financing for our customers for well over 20 years.

Whether the phone system is a VoIP Cloud Phone System Solution, or is a VoIP On-Premise Phone System Solution, both solutions will involve some hardware such as VoIP phones, and if needed, updating the firewall and data switches that need to be installed on the customer’s premises, all of these costs can be financed.
