How does Virtual PBX work?
A virtual PBX works with the help of the internet. It uses VoIP (Voice over Internet Protocol) to transmit voice signals. Unlike traditional PBX systems that have on-premise servers, a virtual PBX has its server hosted on the cloud. All the telephony data like phone numbers, call flows, call notes, call routing, etc. are stored in this cloud server as well.
In a virtual PBX scenario, when a call is placed, the voice data is transferred through the internet and to the recipient’s location. In case, the recipient has a traditional PSTN phone, the virtual PBX uses what is known as SIP trunking to connect the call to the desk phone. Otherwise, it would connect directly to the end user’s laptop, PC, mobile phone or VoIP enabled phone which is configured to receive calls.
