What is a SIP Trunk

Everyone knows what a phone line is. Companies use POTS lines and PRI lines that connect to their PBX in order to make outbound calls. Most companies need to dial 9 or some other programmed number in order to make outbound calls using their Phone Company provided lines (Pots, PRI, etc). A SIP trunk on the other hand uses the internet to connect to your ITSP in order to make outbound calls. It is true voice-over-IP for outbound calls.

In technical terms, SIP (session initiation protocol) is the protocol that enables the PBX to utilize the internet to carry voice traffic. A trunk is a line that can carry multiple signals at once. Therefore a SIP trunk is a way to carry multiple phone signals/calls at once using the internet.

What can I use a SIP trunk for?

The same things you use your phone lines for. If you are a company that has a PRI line, the PRI line allows you to make multiple phone calls at once. A SIP trunk allows you to do the same thing. In general  it allows the following minimum features:

  • Initiate and receive local calls
  • Initiate and receive long-distance calls
  • Make emergency calls (911)
  • Access directory assistance
  • Use fixed and mobile telephone sets
  • Employ e-mail and texting
  • Browse the World Wide Web.
  • Instant messages, multimedia conferences, user presence information
  • other SIP-based, real-time communications services.

What is the benefit of SIP trunks over traditional phone lines?

A SIP trunk is quicker and easier to set up unlike its traditional counterparts. A PRI line can sometimes take up to weeks to provision while you can provision a SIP trunk within a few days.

Also to add additional channels on a PRI line for example is very stressful and time consuming, while SIP trunks have the flexibility to increase the number of concurrent calls a company can make at any time.

SIP Trunks are usually cheaper than its counterparts.

I currently have multiple PRI lines. How do I migrate to a SIP Trunk?

First, you need to ensure that your internet connection has enough bandwidth to support the number of calls you will be making. Once you are sure that bandwidth is not an issue, then you contact us to set you up on our SIP Trunk service. We’ll give you the details of the configuration to input into your phone system so that instead of routing outbound calls to your PSTN gateway, you route it to the newly provided SIP trunk.  Once service is operational you can cancel your PRI, BRI, POTS subscriptions.

What about redundancy? How do I ensure that I never go down?

With SIP trunk, no longer do you have to worry about redundancy to both your data and voice network. Now you can reduce the cost and complexity of your network by only establishing redundancy to your data network. Because SIP goes over the internet you only need to ensure that you have enough redundancy to meet your needs.

I don’t have the money or the expertise to make my network redundant. Is SIP still for me?

The cost of redundancy is not as steep as most people think. Contact us at VeeMost to review your current network so that we can provide you with an affordable, cost effective solution to meet your needs.

What about Quality of Service?

With our SIP trunk services, the quality of service is as good as the PSTN, provided you have enough bandwidth. However, we always recommend configuring QOS (quality of service) on your edge devices to ensure that voice calls take priority over other types of traffic. For example, without proper QOS,  someone downloading a movie file from the internet can cause voice quality issues for all users.

We offers QOS configurations services for customers without the in-house expertise to configure a proper quality of service on their network.
