Open-source telephony

Open-source telephony refers to communication systems that use software and technology that are publicly available for anyone to use, modify, and improve. Unlike traditional systems, which are often proprietary and owned by specific companies, open-source telephony allows developers and users to work collaboratively. This can lead to more flexible, cost-effective solutions for voice calling, video conferencing, and messaging. Popular open-source telephony projects include Asterisk and FreeSWITCH, which provide the tools needed to set up and manage communication networks without the constraints of commercial software.
