SIP-VoIP Phones
A SIP phone is a physical or software-based device that uses the Session Initiation Protocol (SIP) to make and receive calls over the internet. SIP is a protocol that manages multimedia communication, including voice calls, video conferencing, and messaging. Essentially, SIP phones use the internet and a technology called Voice over IP (VoIP) instead of traditional phone lines.
