Bring SolSwitch Inside Your Environment

Take advantage of customizable features, modern functionality, AI tools and advanced routing while keeping call control and data on-site.

Ideal for organizations with strict compliance requirements, private networks or locations where an on-premise PBX delivers the best mix of control, resiliency and long-term cost savings.

Why Choose an On-Premise PBX?

On-premise keeps your phone system, hardware and data inside your own environment - with full control and a lower total cost of ownership over time.

Key Advantages

  • Full control over where your hardware and data live.
  • Deep integration with your LAN/WAN, firewalls, QoS and private circuits.
  • Works with your own carriers and SIP trunks.
  • Local survivability - keep calling even if the internet is interrupted.
  • Lower total cost of ownership over the life of the system.

Frequently Asked Questions

A business phone system is like the brain behind making and receiving of calls for an organization. Also known as a PBX (Private Branch Exchange), it is often a mix of hardware and software that handles routing and switching of calls between a business and the telephone network.

Originally, the 'PBX' was nothing but a switchboard operator. It's name originates from the way it interacts with the PSTN (Public Switched Telephone Network).

Today, phone systems such as the SolSwitch, have evolved into suites of Unified Communications tools that cover a wide range of corporate telecom needs.

Yes. SolSwitch is the same core platform whether it’s on-premise or in the cloud. Many customers start on-premise and later move locations or user groups to a hosted model.

With on-premise SolSwitch and local trunks, we can design site survivability so your PBX continues to operate for internal and, where possible, external calls during outages.

In many cases, yes. SolSwitch can connect to compatible SIP providers for voice and SMS while also leveraging Sunwire services where it makes sense. Compatibility is validated during design.

For mission-critical environments, we can design HA pairs and load-balanced clusters using SS1000 and SS4000 appliances so your architecture matches your uptime targets.

Yes. SolSwitch supports multi-tenant deployments with tenant/carrier licensing options. MSPs and telecom providers can operate SolSwitch as part of their own service stack.

Timelines depend on the number of sites, users, carriers and integrations, but most single-site deployments can be scoped, configured and cut over within a defined project window. You’ll receive a clear plan before we begin.

Sunwire can provide you with a local number to any area in North America, a toll-free number or short codes for SMS texting.

Although each company has a unique set of communication requirements, the most popular items that businesses typically look for in a communications platform include:

  • Support: The ability to fully support customers before, during and after deployment. Downtime is costly - this should be considered when choosing a communications solution.
  • Reliability/Redundancy: We understand the importance of ensuring your business is operating as best as possible. Sunwire provides advanced support options, high-availability and load-balancing systems as well as a wide-range of additional redundancy options.
  • Features/Functionality: Systems must perform so much more than tasks of just a phone system. The SolSwitch has 100s of customizable unified communication features and functionality.
  • Security: Sunwire is pursuing SOC 2 attestation (target 2027). As a Cybersecurity and IT provider, our experts are very familiar with safeguarding information.
  • Costs: The main reason companies move away from traditional systems to VoIP systems are for cost-savings.
  • Scalability: Growing your communication system as you grow your business is not only easy and cost-effective - it can all be done with quickly and at your pace.
