What Is SIP Trunk Protocol?
SIP trunking is also called SIP trunk protocol. This refers to a type of service that replaces traditional phone lines with internet-based phone service.
SIP protocol is typically applied to VoIP networks, and simply initiates and closes communication sessions over the internet. SIP can be used for a variety of purposes, like sending instant messages, conducting a video conference or making phone calls.
In order to transport voice information over the internet, the audio signals need to be converted into data. This is done through the use of codecs. These encoded packets are then transported using a specific transport protocol. SIP packets are also transported by protocols on another layer of the transmission.
Since SIP isn’t involved in the encoding and transmission of data, it’s become the industry standard for VoIP data transmission.
How SIP Trunking Works
SIP trunking is an integral part of business VoIP systems. With VoIP, the call is traveling over the internet instead of traditional phone lines. SIP trunking extends the functionality of a VoIP system by allowing you to make and receive phone calls, even on traditional phone lines.
SIP trunks are made up of multiple channels where the calling data will transfer between. The price you’ll pay for a SIP trunk provider depends on the maximum number of calls you’re making at the same time.
How SIP Trunking Can Benefit Your Business
Most businesses move over to SIP trunk based phone system due to massive cost savings. In some cases, your business can realize savings of up to 50 percent.
Beyond being cheaper to set up and implement, there are a few other reasons businesses love using the SIP trunk protocol:
