April 27, 2023 – ISSABEL, LLC announced today that TMC, a global, integrated media company helping clients build communities in print, in person and online, has named Issabel Unified Communication Platform as a 2023 Unified Communications Product of the Year Award winner.

Issabel Unified Communication Platform, is an Open Source (News - Alert) Development now with more than  500,000 implementations in more than 200 countries.

It includes a call & contact center module with all the related functionalities for IVR, TTS, ASR, ACD for inbound and outbound, call and contact center, recording, multitenant, etc.

Issabel is an open-source Unified Communications PBX (News - Alert) software, providing user-friendly web-based configuration, management, and reporting for telephony. Modules providing predictive dialing, call and contact centers can be added. It is a fork of the open-source versions of Elastix (News - Alert), developed by the user/developer community when 3CX acquired Elastix, closed the community, halted distribution and development of the open-source versions, and released a proprietary version.

Issabel is based upon open-source versions of Elastix, Asterisk (News - Alert), FreePBX, HylaFAX, Openfire and Postfix, and provides PBX, fax, instant messaging and e-mail server functionality. Issabel is open-source software licensed under the GNU Public License.

“Isssabel offers both a single-tenant and a multitenant version, depending on the needs of our clients and distributors,” Said Boris Garfias, CEO, Issabel. “We also offer the acquisition options that make the most sense for customers, including traditional on-premises purchase or as a cloud-based managed service offering.”
