The database files are physically stored in /var/lib/postgresql unless otherwise specified during installation. The basic package includes additional modules: TimescaleDB Webitel Extension
Consul	A critical piece of architecture. Decentralized fault-tolerant discovery service from HashiCorp. Every application (except PostgreSQL, RTP, OpenSIPS, and Nginx) registers with this service.
rabbitmq	A critical architectural element. Messaging bus between services: OpenSIPS - publishing device registration statuses and dialogs FreeSWITCH - publishing statuses of dialogs and execution of voice applications Webitel - publishing, and reading user statuses and voice channels Messages - publishing text applications Engine - publishing and reading user statuses CallCenter - publishing and reading agent statuses. Publication and reading of work statuses of dialers Flow - publishing and reading the execution statuses of voice and text applications Storage - read dialog statuses
OpenSIPS	SIP Proxy - provides signaling protocol (SIP/WebRTC)
RTP	rtpengine - provides multimedia protocols
FreeSWITCH	Voice media server. Allows to create an IVR menu and combine voice channels. The basic package includes additional modules: Webitel GRPC AMD - work with autoresponders AMQP - work with rabbitmq Transcribe - asynchronous work module with STT PUSH - support for PUSH messages for registrations on mobile devices (iOS/Android)
nginx	Application Web Server. Provides HTTP REST API and WebSocket proxying.
