This lightweight and efficient tool is designed to provide high-quality VoIP (Voice over IP) communications, using modern codecs and an easy-to-use interface. If you want a tool to make voice calls with the highest quality, download MicroSIP for free.
High audio quality
One of MicroSIP's strengths is its ability to provide high-quality voice calls using modern codecs such as OPUS, G.722, G.711, and G.729. These codecs are designed to optimize audio quality and reduce latency, ensuring that conversations are clear and uninterrupted. The app automatically adjusts the audio quality according to the available network connection, providing the best possible experience in various network conditions.
Support for multiple SIP providers
This software is compatible with various SIP service providers, allowing you to choose the best service. Setting up a SIP account is simple and can be done in just a few steps, allowing quick integration with your preferred VoIP service. This flexibility makes MicroSIP a viable option for both individual users as well as small and medium-sized businesses.
Advanced call functionalities
Despite its simplicity, MicroSIP offers several advanced features that enhance the user experience. These include making and receiving calls, transferring calls, providing support for multiple lines, and placing calls on hold. In addition, the app supports integration with the Windows address book, making it easy to manage contacts and make calls.
Lightweight and efficient
MicroSIP is designed to be a lightweight and resource-efficient app, making it ideal for systems with limited hardware capabilities or for users who want to minimize the impact on their system's performance. The app runs efficiently in the background, allowing other apps to continue running smoothly while VoIP calls are made.
Security and privacy
Security is an important consideration in VoIP communications, and MicroSIP addresses this concern by supporting encryption protocols such as SRTP (Secure Real-time Transport Protocol) and TLS (Transport Layer Security). These protocols ensure that voice calls and transmitted data are secure and protected against unauthorized interception, providing users with an additional layer of privacy.
