Details and Implementation

New or Legacy PBX Phone Systems

Our service is standards-based which ensures compatibility with your existing PBX. We are compatible and certified with all major phone systems.

If you have a legacy PBX and are using a PRI (Primary Rate Interface) for your network connection, we can provide a gateway to covert PRI to SIP so you can save money and keep your current PBX.

Multi-Site & Remote Phones

You can extend your savings by sharing our minute plans across multiple locations. Why pay for excess minutes at each location if you don’t have to?

Our support for remote phones and our ability to verify the E911 location address with a phone call protects your employees and your business.
