Inbound SIP Trunking
Inbound SIP Trunking is a communication service that allows businesses to receive incoming calls from external sources like customers or clients. It works by linking the business's phone system to the public telephone network via a SIP trunk provider.
E.g: When a customer dials your business phone number, the call is routed to your SIP trunk provider over the internet, who then forwards it to your phone system.
Outbound SIP Trunking
Outbound SIP Trunking is a telecom process that allows businesses to make outgoing calls to external sources like customers or clients. It operates by connecting the business's phone system with a wider telephone network through a SIP trunk provider.
E.g: When a business makes a call via its virtual phone system, the call is routed to the SIP trunk provider over the internet, who then forwards it to customers or clients.
