The Redmi Note 14 5G doesn’t support SIP calling. SIP (Session Initiation Protocol) calling is a protocol used to make voice and video calls over the internet, commonly used for VoIP (Voice over Internet Protocol) services. It enables communication between different devices or platforms (such as smartphones, computers, and IP phones) through an internet connection rather than traditional mobile networks.
The main characteristics of SIP calls are as follows:
1. Voice and video calls: SIP allows for both voice and video calls;
2. Low cost: SIP calls typically cost less than traditional cellular calls, especially for long-distance communication;
3. Cross-platform: SIP can work across different devices and platforms, including smartphones, desktops, tablets, and even specialized IP phones;
4. Flexibility: SIP is highly flexible and used by a wide variety of communication apps and services, including business solutions like VoIP phones, conferencing apps, and more.
