SIP Trunking and Voice Lines

With the vast array of options available for your business phone system, choosing the best combination of service to suit your particular business needs can be a challenge. You need a business phone system provider that is qualified to assess your unique requirements and recommend the ideal solution for your business—a partner with the knowledge and expertise to create an effective communications environment that will enable your employees to seamlessly collaborate.

Activo provides a range of voice solutions including SIP trunking, PRI services, and analog trunks. We can provide on-premise or hosted solutions and provide end-to-end lifecycle support, from design through to installation and ongoing support

SIP Trunking

SIP trunking is a protocol that sets up sessions of multimedia communications (both audio and visual) between endpoints via a wireless connection or a Virtual Private Network (VPN). This can replace multiple PRI connections with a flexible system that helps enable IP telephony solutions like VoIP.

Activo provides business-grade SIP trunking for businesses and organizations from coast to coast. We have a physical presence in TOR 1, Canada’s largest data centre, and use network-to-network interfaces (NNIs) in order to ensure your voice lines are supported by the carrier capable of providing the highest quality services, fastest speeds, and cost-effective solutions.

Other Voice Lines

In addition to SIP trunking, Activo also provides the following voice lines:


A PRI (Primary Rate Interface) is a telecommunications interface that is used to carry up to 23 channels of voice, data, video, and other traffic.


Analog voice lines are able to carry and transmit voice and fax signals. Though they don’t tend to require significant upfront investment, they are also the least scalable and versatile.

Other Voice Services

Direct Inward Dialing (DID)

DID allows a company to assign personal numbers to individual employees without needing a wholly separate phone line, making it easier to manage telephony traffic.

Long Distance

Depending on your needs, Activo can provide North America-wide long distance for analog, PRI, and SIP trunking voice services.

SIP Trunking and Voice Lines Frequently Asked Questions

What makes SIP trunking such a flexible solution?

The two main benefits associated with SIP trunking are the ability to burst dynamically and seamlessly handle the increased load if you go over.

In considering SIP trunking for my organization, what are some of the factors I need to take into account?

You will want to think about things such as:

  • The number of people who will be on the phone at the same time, as this will affect the number of channels you need.
  • Whether or not call volumes stay consistent or tend to fluctuate. The benefit of a SIP trunking solution, though, is that it is typically highly scalable.
  • If you will need to accommodate more than just voice calls. Will you be using video conferencing, for example? In call centre environments, will agents be communicating with customers through alternate methods like online forums?

To discuss your organization’s specific needs more in depth, contact Activo today.

Can I keep my existing endpoints and other technology?

This varies on a case-by-case basis, but many modern phones are compatible with SIP trunking and other IP telephony solutions.

Do I need SIP trunking with VoIP?

You can have a VoIP phone system without employing SIP trunking, however to take full advantage of VoIP’s capabilities (particularly multimedia communications), SIP trunking is crucial.

Can SIP trunking be run over the top?

It can, however we recommend using dedicated bandwidth (preferably a Layer 2 connection) to ensure quality of service.

What is QoS and why is it important?

Quality of Service (QoS) is the ability to deliver improved service to select traffic transmitted over your networks, the ultimate goal being to provide dedicated bandwidth [Link to bandwidth page]and control over jitter and latency.

QoS is vital for voice communications. If voice packets are delayed, interrupted, or dropped when networks become busy and clogged with traffic, that negatively impacts call quality and makes conversations choppy. A QoS helps to minimise packet loss and maintain standards even during the busiest network periods.
