SIP Trunking

Connect Your Hardware PBX to the Cloud and Save

There are many businesses that continue to rely on an on-site PBX. Whether they do so to maintain complex call routing structures, custom integrations, or existing hardware – there is no obligation to pay traditional service providers to deliver call traffic. Much like a fully-fledged hosted PBX solution, VoIP (Voice over Internet Protocol) can be used to deliver your physical PBX system’s call traffic over the internet with SIP Trunking. Because SIP Trunking allows you to use a service that you already pay for – your internet connection – to deliver call traffic, it is extremely cost-effective. It’s also extremely easy to set up. In just a few clicks, you can deploy your SIP Trunking solution. You’ve already done the heavy-lifting to configure your PBX system, start paying less and getting more from it today.

Cut Costs and Scale at Any Time

Local voice trunks and PRI lines are expensive, but luckily, they’re not the only option for companies looking to maintain an on-site PBX. SIP Trunking offers a much lower cost per minute for voice traffic and can often allow companies to consolidate communications providers. But perhaps the most attractive advantage is the ability to scale up or down with ease whenever you see fit.

  • SIP Trunking Plans from VirtualPBX start with 20 channels – allowing up to 20 concurrent calls at any time.
  • Need to scale up to add more channels during peak holiday traffic? No problem! Additional channels are available at $3.99/month each.
  • Each plan also includes 5 additional burstable channels, allowing you some extra margin during a burst of traffic.
  • Manage the usage of your channels with the help of our SIP Trunking experts who provide alerts and guidance when it’s time to scale.
