Simply put, what is an IP phone?

The IP phone number is17908 \17909 \ 200 \ 201. Of course, there are also callback calls such as 950527 or other IP phones, which are generally operated by telecom operators. The above IP phone does not need an IP address, just enter the access number directly and listen to the voice prompt.

Calling through the network is called VoIP, not IP phone.
