SIP Origination

International SIP Origination (SIP Trunking)

Our Session Initiation Protocol (SIP)-based wholesale origination service uses an IP peering interface that allows our customers (mostly retail and wholesale service providers) to receive traffic originating from the PSTN using a simple SIP interface.

What is SIP origination?

SIP origination refers to the collection of voice calls from the PSTN (POTS) and subsequent conversion to SIP.

We hand off PSTN-originated voice traffic to our carrier customers for termination to the called party. Calls are originated and collected as TDM, converted to SIP and forwarded on our private IP backbone.

We then hand the calls back to you via a dedicated IP connection, or through the Internet, for termination to anywhere in the world.

Benefits of international SIP origination

With Voxbone you can easily get SIP origination from a remote area, city, or even from a foreign country and receive all incoming calls at one location.

In the old PSTN days you had to order a PRI (E1 or T1) and colocate an equipment in each of the countries from which you wanted to collect traffic. This results in high costs, and a long time to market.

Now you can get a virtual E1 or T1 that covers all our cities in just a few minutes.Just configure the capacity that you need and from which cities you wish to collect, and we do the rest!

Example use cases for international SIP origination
  • Multinationals

    Your headquarters are in New York and you have offices in the United States, South America and Europe.

    You wish to get rid of all the existing physical voice lines in your remote offices and you wish to centralize all European originated phone calls to your London office, and all US –and South America originated phone calls to your New York office.

    By porting your existing numbers to Voxbone you can achieve this in 50 countries without changing your phone numbers.

    You have customers all over the world and need to provide them with a local phone numbers from their respective countries.

    You cannot afford to wait several years before launching this service and need someone that can provide you instant access to phone numbers from as many countries as possible. You also need to support number portability such that your customers can keep their existing numbers when moving their telephony to your network.

  • Calling card providers

    You wish to provide a calling card that offers cheap and good quality calls to Pakistan and your target are all the Pakistan expatriates around the world. With Voxbone you can immediately get access numbers from about 50 countries and start selling your calling card in all these countries.

Voxbone will collect these PSTN originated phone calls and will forward these calls to your IVR using VoIP.
