MicroSIP at a glance
MicroSIP is an open-source SIP softphone for Windows built on the PJSIP stack. It registers with the SIP servers of VoIP providers or an on-premises PBX and gives administrators a lightweight client for voice and video calls. Typical features include multiple accounts, an address book, call logs, DTMF, call recording, and optional transport encryption.
New editions are published at irregular intervals as standalone full releases with an incrementing version number; the program does not include an automatic updater. The maintainer provides installers and portable archives on the project site and keeps a changelog for each edition. Alongside the standard package there is a Lite edition as well as 32-bit and 64-bit builds.
When updating, administrators should check that the chosen edition (standard, Lite, portable, architecture) matches the existing installation and back up configuration and accounts. Because distribution and updates are manual, managed environments benefit from a package source or software-deployment tool to preserve settings and roll out security fixes promptly.
