Overview

We’ve made building your FusionSIP Trunking solution simple through our straightforward, yet flexible packaging. Follow the steps below and, of course, we’re always here to help.

  • Determine if your PBX is supported
    Check out our IP PBX Interop list to see if your PBX manufacturer has participated in our interop program. Don't see your manufacturer on our list? We still want to talk to you! We’re confident in our ability to support your PBX and can even confirm interoperability - before you buy - through our SIP Trunk demo program.
  • Select your Calling and Usage Plan
    Flexible calling and usage plans ensure your business is billed in the manner you desire.
  • Determine the number of concurrent call paths you need
    Unlike PRI lines which contain 23 channels, Fusion SIP Trunking can be purchased in increments as low as one concurrent call, so businesses buy only what they need as they need it.
  • Choose your required add-ons
    Advanced business continuity, call bursting, and other options provide increased flexibility with your Fusion SIP Trunking solution.
