Mobile Integration

Mobile Peripherals and SolSwitch Mobile Features

We offer multiple ways to integrate your mobile devices with the SolSwitch Phone System. Third-party soft phone apps allow you to connect directly to the phone system, log into your extension and use your mobile device as if it were your desk phone. The system also has intelligent call routing features such as those listed below:

Virtual Extension Office Connection Desk

Assign external telephone numbers to a local extension on the system. Ideal for sales representatives and field technicians who travel but need to stay connected.

Find-Me Follow- Me Him Them Her

Reach a user by calling a succession of extensions or external numbers while keeping the incoming call on hold. Great for after hour staff or a replacement to voicemail.


Reporting and Monitoring Tools

We offer a wide variety of analytics to help make your business more efficient - contact us for a full list of reporting tools.

System Security

The SolSwitch Guardian ensures your business' phone system is protected.

  • Device Provisioning Monitoring
  • Unauthorized IP Blocking
  • Flood and Packet Protection
  • Web Portal Login Blocking
  • Brute Force Prevention
  • Call Pattern and Volume Alerts

SIP security, like any technological security, is a vast and somewhat challenging field. Rolling out a public SIP service can sometimes bring with it several security concerns.

This is why the team at Sunwire has developed and incorporated the SolSwitch Guardian into all of its phone system solutions. Using proprietary techniques, the SolSwitch Guardian ensures that only authorized devices may provision on your phone system.

SolSwitch Guardian also includes monitoring and notification tools that can be configured by the administrater in order to receive alerts in the case of any unusual activity.

We take the security of our systems very seriously.

    Multi-Tenant Partnership agreement is required.

Backup Options

We offer two redundancy options that can be implemented individually or together.


Ensure you're always up and running.

High Availability refers to a system or component that is continuously operational for a desirably long length of time. HA works by connecting and syncing two appliances together.

One system is active and the other is on stand-by. Should the active unit fail, the stand-by system instantly becomes active with no active calls being affected thereby ensuring constant connectivity.


Ensure your system is never overloaded.

Distributed Load-Balancing is a computer networking methodology to distribute workload across multiple computers or clusters. SolSwitch’s Load-Balancing involves having two synced systems at separate locations.

In the event that one location suffered a catastrophic accident, the other location could continue to operate and support the phone system without down-time.
