You can imagine a conference call as a hands-free form of a regular phone, with enhanced 360 degree amplification and sound pickup on top of hands-free technology, and the use of echo cancellation technology to make calls clearer.
Regarding multi-party communication:
The phone actually only supports multi-party communication, and this specific function is a service provided by the operator. We need to activate this function on the phone lines used by China Mobile, China Unicom, and China Telecom.
Various ways to achieve multi-party communication:
1. Purchase conference platform
2. Through some switches (if your telephone switch supports multi-party communication)
3. By renting a conference platform
4. Services provided by telecom operators (such as China Telecom, etc.)
