Virtual SIP Server.

Do you not have a SIP server but still want to provide VoIP or calling card service to your customers? We have a ready-to-use solution for you. Our VPS platform will allow you to manage your customers, their ATA devices and set call rates you charge the customers. The billing core is built with asterisk2billing open source software, visit the a2billing web site to find more information about a2billing capabilities and view the documentation.

Our VPS platform includes the following components:
  • Virtual linux server running on quad core Intel Xeon CPU, 1 dedicated public IP address.
  • Asterisk PBX and a2billing software with CWU trunks and our wholesale rate decks preconfigured (please keep in mind that the rates are out of date and are provided as an example only).
  • Disk space to host your web site.

The virtual server platform price is $10 to set up and $15/month.
