The VoIP gateway works in a simple way. In order to work, VoIP gateway needs a decent amount of traffic. When the VoIP gateway gets enough traffic, it begins to convert traffic into an acceptable form, according to the origin. 

After that, this convenient form of traffic is received by the destination network. If the traffic generates from PSTN (Public Switched Telephone Network), the VoIP gateway converts the analog voice signal into a digital one. And that is how the transmission of the digital signal takes place after using a suitable signaling protocol. 

To continue this transmission process, more digital signals need to be converted into a series of packets. In order to have a proper workflow, a codec and protocol are also necessary. However, it is important to ensure both the protocol and codec are compatible with the VoIP phone system.
