How does 3CX support video calls?

3CX supports video calls primarily through the SIP (Session Initiation Protocol) with compatible devices. SIP is a signaling protocol widely used for initiating, maintaining, and terminating real-time sessions in voice and video calls over IP networks. By leveraging SIP, 3CX allows for compatibility with a wide range of devices, including IP phones, softphones, and video endpoints that adhere to the SIP standard. This means users can enjoy high-quality video calling capabilities using their existing internet infrastructure and compatible hardware.

SIP's versatility and integration capabilities allow 3CX to offer video conferencing features that work seamlessly across various platforms and devices, enhancing communication in both personal and business contexts. This is particularly useful for organizations that utilize multiple devices and need a reliable method for video communication without being limited to specific hardware or software solutions.

In contrast, other options are more restrictive or specific in their application. For instance, using the WebRTC protocol exclusively would limit compatibility to certain web-based applications and clients instead of the broader range of SIP-compatible devices. Integrating solely with webinar platforms would not provide the comprehensive video capabilities that many users require for regular communication. Finally, relying on traditional PSTN lines would not support video calling since those lines are designed exclusively for voice communication without video transmission
