Transport defines how SIP signaling is transmitted between PBX and endpoints.
Supported protocols include:
- TCP: Reliable, but resource-intensive.
- TLS: Secure communication.
- UDP: Lightweight and fast but prone to packet loss.
- WS/WSS: Used for WebRTC, with WSS offering encrypted transmission.
Edit Transport to choose the default one that will be used for extensions and trunks. You can also change the Bind Port.
- Note: Only one transport protocol can be set as the default.
