A Session Initiation Protocol (SIP) IP phone, often referred to as a SIP phone or VoIP phone, is a device that enables voice communication over the internet. Unlike traditional landline phones that rely on the Public Switched Telephone Network (PSTN), SIP phones leverage an internet connection to make and receive calls.
SIP IP phones offer several advantages, including cost-effectiveness, flexibility, and advanced features. They eliminate the need for expensive landlines and long-distance charges, making them an attractive option for businesses and individuals seeking affordable communication solutions. Additionally, SIP phones provide the flexibility to make and receive calls from any location with an internet connection, empowering remote work and mobile communication. Furthermore, these phones often support advanced features such as call forwarding, voicemail, and video calling, enhancing communication capabilities.
