    Hello, everyone! I have been developing, implementing and setting up call centers for my clients for more than 10 years. The most popular and stable systems are Vicidial and FusionPBX. The whole process can be divided into 3 stages: 1 - Discussion with the client of all wishes and requirements for the system. Discussion of necessary equipment based on information received from the client about the size and location of the call center. 2 - Drawing up a project plan and deadlines for its implementation, as well as agreeing on prices and payment methods. 3 - Launch and support of the call center until stable operation is achieved. During my work, I have launched and supported many call centers. Many of them are still working today. My primary areas of expertise are: - FreeSWITCH - Kamailio, OpenSIPS - Programming languages such as Python, Lua, PHP, Node - Database management using PostgreSQL and MySQL - Server administration, Docker, and AWS.
