Phone number service SIP Trunk
What is a SIP Trunk?
SIP (Session Initiation Protocol) Trunking is the process of connecting IP PBX devices to a telephone exchange using the SIP protocol for communication over an IP network. This provides a more flexible and scalable communication system than traditional telephone lines.
Simply put, SIP Trunk services allow businesses to use their 02 or corporate phone numbers over the internet instead of traditional copper wires.
How does a SIP Trunk differ from a SIP Account?
A SIP account is suitable for individual users or small businesses that want to use a single phone number per device, and typically limits the number of simultaneous calls.
SIP trunks are ideal for organizations that need to connect directly to a PBX (Private Branch Exchange). They support concurrent calls through a single number, making them suitable for businesses with high call volumes, such as call centers.
Protollcall’s SIP Trunk service is ideal for organizations that require more flexibility to handle a large volume of calls than typical SIP accounts.
