StarSIP works with virtually any PBX system, using a small on-premise device called a StarSIP Integrated Access Device. This device allows us to deliver SIP services over a standard broadband Internet connection. You don’t need expensive MPLS or dedicated private IP connections.

Star2Star provides three ways to connect your PBX to StarSIP trunks, depending on the capabilities of your existing PBX:

  • For SIP-capable PBX systems, the Integrated Access Device connects directly to your existing PBX, replacing your existing SIP trunks
  • For ISDN PRI/T1 connections, we provide an IP Gateway device to deliver 23 voice channels per PRI connection
  • For POTS-based PBX systems, we use Cisco IP Telephony Gateway devices to deliver up to 40 analog trunks using standard RJ-11 or RJ-21x connectors
