What is SIP phone calling and how it works?
Poor communication solutions can cost businesses billions. Historically, communication solutions were limited to copper wire-based networks such as PSTN and ISDN. The Public Switch Telephone Network (PSTN) exchanges are public phone networks that use legacy phone lines for communication and are not designed for high-speed internet connection and business communication. The Integrated Services Digital Network (ISDN) exchanges use PRI (Primary Rate Interface) connections to manage high video conferencing, however, they aren’t scalable. Voice over Internet Protocol or VoIP Business has become the go-to technology for corporate communications because of VoIP services scale with businesses growing traffic needs. However, to add chat, video conferencing and chat you need the SIP (Session Initiation Protocol) trunking.

What is SIP Trunking?
SIP calling connects customers and offices without using legacy telephone systems.
SIP reduces businesses dependence on hardware solutions like PSTN and PRI solutions. With less hardware and with internet-based communication businesses can run smoothly while becoming more cost-efficient.
A SIP trunk is a virtual connection, used for SIP calls. With SIP you can make local, international and long-distance calls through the internet. This protocol connects you and other participants to a single channel and the connection is changed when the conversation is completed. The great feature of SIP is that it allows multiple communication sessions simultaneously. Other than voice communication SIP is used to send any type of non-voice communication over the internet, for sharing files, chatting and conferencing, making it ideal for start-ups and small businesses.
What is a SIP Phone System?
Handsets used with SIP can be connected to the modem directly; they don’t need a connection to a computer.
SIP phone system needs IP desk phone and handsets to connect with internet to reach PSTN networks. On the other hand, VoIP needs a VoIP phone to be connected to a computer with an internet connection. VoIP uses SIP protocol which opens and closes the connection during a call. SIP phones are similar to standard phones but they need a wired connection to work. You can also wire a SIP device to a computer which is not turned on to make and receive calls. If you don’t want to use SIP desk phones then you can use softphones as well.
Why Businesses Use SIP Calling?
There are a lot of reasons why businesses prefer SIP call; we are going to enlist some of these reasons below:
According to research, businesses waste a huge amount of money on ineffective communication solutions. But with SIP, a business can save almost 40% on local and long-distance phone calls alone. However, if your business makes international calls frequently then the amount that you can save increases drastically. SIP can help your business save up to 90% or more for international calling. International calling rates for SIP are much cheaper than traditional telephones. You save more by eliminating unnecessary hardware, installation, maintenance and multiple networks cost. SIP trunks only need a VoIP gateway or an IP-enabled PBX IP service to connect your traditional PBX to the cloud.
Better Call Routing
With SIP you can route incoming calls to other workstations or to mobile phones. This makes you more available to customers and colleagues when you are not in the office
Scale Base On Business Growth
If you try to increase scalability on PRI configuration then you will need to get more phone lines which are only available in clusters of 23. This means you have an extra 22 lines for calling which you may not need. But, with SIP you don’t need to buy excess lines because you can buy a single line at a time.
SIP trunks transmit both data and voice, so you will be able to incorporate it in several inter-business uses such as unified communication. This ties file sharing, voice calling, video calls and instant messaging into your business’s communication solution. VoIP providers use SIP in phone plans because VoIP calls work only with voice data packets, the core of SIP calls.
