Session Border Controller (SBC)
Sinch Contact Pro needs an external SBC system to translate incoming Communication Panel traffic from WebRTC to SIP. For handling that SIP traffic, Sinch Contact Pro needs a dedicated SIP Bridge module.
The image below shows the traffic between these components.
-
An agent logs in to Communication Panel.
-
Communication Panel receives SBC address and SIP identity.
-
Communication Panel sends a SIP REGISTER message.
-
SBC creates a new SIP REGISTER message with the SIP identity to the received SBC address.
-
WebRTC SIP Bridge sends the received REGISTER message to Agent Server.
-
If the authentication is successful, Agent Server informs WebRTC SIP Bridge.
-
WebRTC SIP Bridge sends a 200 OK for REGISTER message to SBC.
-
SBC sends the message to Communication Panel.
