The SIP Phones are the phones that utilize Open Standard Session Initiation Protocol (SIP) to manage and set up calls using other Open Standards called the Real-time Transport Protocol (RTP). These protocols are all generically termed as Voice over IP and thus, the phones are also commonly referred to most times as VoIP clients or VoIP Phones. There are two main categories of SIP Phones namely, Software Phones or SoftPhones and Hardware Phones or HardPhones.
Hardware Phones or HardPhones
A HardPhoneis something that bears resemblance to regular phones and also acts like one. However, in this SIP Phone the hardware is made using IP-aware parts. This one will connect to the IP networks using Wi-Fi or Ethernet. You will also get cordless phones in HardPhones. The cordless phones use the DECT technology whereby the phones connect to a base station through DECT protocol. The base station connects with an IP PBX using RTP and SIP transport protocols.
Software Phones or SoftPhones
The function and nature of SoftPhone is evident from its name. It is a software program that gives the functionality of a telephone. Just like a HardPhone, a SoftPhone utilizes RTP and SIP for voice delivery and call setup. Any device like desktops, tablets, and smartphones can be used to run SoftPhone programs provided it has speakers and a microphone. The main requirement is the IP connection to the SIP server or VoIP provider through IP PBX.
