SIP phones and IP phones are often used interchangeably — and in practice, they almost always refer to the same thing. An IP phone is any phone that makes calls over an IP network (the internet). A SIP phone is an IP phone that specifically uses the SIP protocol — which nearly all modern IP phones do.
So virtually every IP phone sold today is also a SIP phone. When shopping for VoIP phones, don't worry about the distinction — just confirm the phone is SIP-compatible, and it'll work with RingVersa. Plans start at $14.95/mo.
