Based on the Session Initiation Protocol, a SIP trunk provides the connection between your network and the public switched telephone network (PTSN). With this SIP trunk connection, you can make phone calls from your IP-PBX device without additional physical wiring, thereby reducing the recurring costs of separate voice and data circuits and the costs associated with the purchase, support and maintenance of media gateways.
Integrated access combines your voice and data onto a common access circuit, enabling you to achieve greater economies of scale and simplify the management and maintenance of your communications infrastructure.

Airvox SIP trunking uses VoIP to allow a PBX to connect to external telephone networks via the Internet.
  • The Internet acts like a traditional telephone line, so a user can communicate with telephone subscribers that use a fixed or mobile telephone service. Airvox uses the SIP trunks to deliver the communications from your PBX to the outside networks, and from outside networks to your PBX.

 • SIP trunks can offer significant cost savings for enterprises, because they eliminate the need for local PSTN gateways, costly ISDN BRIs (Basic Rate Interfaces) or PRIs (Primary Rate Interfaces).
  • Business that have invested in an internal IT infrastructure are great candidates for a SIP trunk because they can easily plug it into their SIP environment – there is no upside to hanging on to existing landlines when there are tools in place for a more easily-managed, lower-cost communications solution from Airvox that is versatile and equally reliable.
  • As SIP Trunking providers, we are able to enhance the capabilities of your software or device by providing a complete solution for all internal and external communications. Whether you have a traditional PBX or Virtual PBX , call center solution or our managed Cloud Phone System , we can help you make the most of your IP investment with a SIP Trunk, which is a combined solution of DID Numbers and bi-directional channels scaled perfectly for your needs.
  • Usually, the the most important aspect of deploying a SIP Trunk is the channel and DID distribution. SIP services from Airvox let you combine these two elements according to your business needs, making it probably the most versatile and scalable solution available on the market.

SIP Trunking is an ideal solution for businesses with an on-premise IP-PBX or migrating to Cloud
