Real-Time Billing Integration with Gateways & Switches

Our web and database-based APIs allow most any gateway or switch to integrate in real-time with the DTH VoIP billing system.

At the moment we have pre-built integrations for Asterisk®, FreeSWITCH and Sansay. If there are other systems you would like to integrate with, please contact us.


Asterisk is an open-source telephony engine released under the GNU General Pubic License. Asterisk runs on a variety of operating systems including Linux, Mac OS X, Open BSD, FreeBSD and Sun Solaris. It is currently the most popular open-source telephony engine available.

Our integration with Asterisk provides near real-time call record billing.


FreeSWITCH is a scalable open-source, cross-platform telephony platform designed to route audio, video, text or any other form of media. It was created in 2006 by a team of former Asterisk developers.

FreeSWITCH runs on many operating systems including Linux, BSD, Windows, Max OS X and Solaris.
