Docker vs FreeSWITCH

Docker

Description: Docker is an open platform for developing, shipping, and running applications. It allows developers to package applications into containers—standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment.

Type: software

Pricing: Free

FreeSWITCH

Description: FreeSWITCH is an open source telephony platform designed to facilitate the creation of voice and chat driven products scaling from a softphone to a PBX and even up to an enterprise-class softswitch. It can be used to power PBX solutions, voicemail services, conference calling, contact center solutions and more.
