Asterisk is an open source PBX and telephony toolkit that acts as middleware between internet/telephony channels and communications applications. It supports VoIP/SIP as well as traditional PSTN and analog telephony interfaces.

Use cases

• run a self-hosted PBX for my office phone system
• build a SIP/VoIP server for making and receiving calls
• set up an IVR with call routing and voicemail
• bridge SIP calls to traditional PSTN or analog phone lines
• build custom communications applications on a telephony framework
• replace a proprietary phone system with open source

When to choose

• you need a mature, battle-tested open source PBX with SIP and PSTN support
• you want a programmable telephony toolkit with a large module ecosystem
• you need to interface with Sangoma or other telephony hardware cards

When to avoid

• you only need simple WebRTC video conferencing rather than telephony
• you want a managed cloud phone service with no server administration
• you need a lightweight embedded VoIP client rather than a full PBX server
