A SIP trunk is a “virtual” phone that may function without physical phone lines, unlike a standard analog phone. Your private PBX may be connected to several SIP trunks from a provider (like Max Link Solutions) so that you can make and receive calls from anywhere in the world via the internet.

Through a packet switch network, calls may be routed through an existing VoIP or PBX system with SIP trunking. Internet phone calls include the digitization of speech into data packets for transmission. In order to answer a call, the data packets are transformed back to their original format.

In order to use SIP trunking for voice over IP, a PBX (also known as an IP PBX) or UC platform that is SIP-compatible must be in place. In today’s remote-first workforce, the flexibility to utilize a single phone number across many devices, including traditional desk phones, softphones, and mobile phones, is a big perk.
