Why SIP Trunking?

With the emergence of low‐cost broadband and VoIP backbones, SIP‐based VoIP trunking is rapidly becoming the standard for interconnecting a business’ premises‐based communications equipment to the PSTN.

SIP trunking offers enterprises many advantages over traditional analog lines or Primary Rate ISDN (PRI) interfaces, including:

  • 30% lower service cost structure
  • Advanced disaster recovery features
  • No Geographic Number Restrictions (move your business without changing your phone numbers)
  • Ability to realize the full cost benefits of IP‐PBXs by providing direct SIP peering and eliminating expensive TDM to VoIP gateways at the customer premises.

Customers can use the Business Trunking solution leverage their current PBX offering with neXfone next generation IP‐based telecom service capabilities.
