Expanding business communications is an important step in fostering business growth, and one of the options companies have today is highly adaptable SIP trunking. An SIP trunk is the connection between your business and your Internet Telephony Service Provider (ITSP). Using an SIP trunk helps your business utilize Voice over Internet Protocol (VoIP) technology without having to employ an IP-PSTN gateway, which is a converter device that translates telephone traffic so that it can be sent over a data network. Using SIP trunking for your business phone service can offer a swift return-on-investment for your business.

SIP Trunking: The Basics and What You Need to Know

When your company decides to use SIP trunking, you’ll have access to business phone systems that are affordable to design and provide simple operation, require limited maintenance costs, and are easily upgradable. ITSPs also offer significant savings for their services, so SIP trunking can dramatically reduce the costs associated with upgrading your business phones or networking capabilities. You’ll have access to local and long-distance calls that all fall under the category of “local,” which means you won’t pay long distance charges anymore, and you’ll also have access to other real-time communication services like instant messaging, user presence data, and multimedia conferences.

How Can My Company Deploy SIP Trunking?

The ease of installation, long-term reliability, and scalable features of SIP trunking are significant reasons why businesses may choose to install the technology, but how do you implement SIP trunking? Vergent’s business phone consulting experts will need to determine which type of connection is best for your SIP trunk. There are three types of connection types, and each offers advantages and disadvantages. Figuring out which connection type will suit your business best is one of the many reasons it’s important to work with Vergent on your business phone upgrade plan.

Connection types for SIP trunking include:

  • Dedicated line without other traffic
  • Dedicated line shared with other IP traffic
  • Public (Internet)

The most reliable option is a dedicated line without other traffic, but this option is also the most expensive.  It’s also the most reliable, most secure, and it offers the highest call-carrying capacity. However, every business – particularly small businesses – won’t have the available budget to use a dedicated line. Alternatively, a business may choose to use a dedicated line that’s shared with other IP traffic and enjoy the security of a line that’s not shared. However, sharing a dedicated line can create issues with VoIP operation when traffic levels are high. A way around this issue is to give VoIP traffic the highest priority for line use.The least secure option is a public connection, otherwise known as the Internet. This option is ideal for small businesses on a very tight budget, but it’s the least secure option and it’s also the least reliable. However, a small business may not need the high call-carrying capacity of a dedicated line, so it may be prudent to start with an internet connection line.

Bandwidth Needs of SIP Trunking

As your business phone consultants, Vergent will conduct a usage survey to determine the required bandwidth for an SIP trunk. There are a few factors that influence the bandwidth required for SIP trunking, but the primary factor is the number of concurrent calls that the system will need to handle.

The basic equation used to determine bandwidth needs is:

Maximum simultaneous calls x 80kbps = Required bandwidth

Vergent provides SIP trunking services, and many advantages exist for businesses that choose to implement this type of technology for their communications needs. Contact the telecommunications experts at Vergent for more information about SIP trunking.
