Transports

Here you can define transports that will be used for SIP signaling. You can then assign the selected transport to SIP channels. If you do not assign any, the transport used by the client will be used.

Transport list

Creating, Editing and Deleting a Transport

Create a new transport by clicking the New Record button located in the top toolbar. Edit by clicking the Edit button. If you wish to remove a transport, click the Delete button. You can also edit and delete by right-clicking on the selected transport.

Transport Properties

Properties

Active — enables or disables the use of the transport
Name — transport name
Data — transport configuration content. Below are examples from Asterisk documentation. Variables that work with values from Global SIP Settings: %BIND_IP% — SIP IP address, %BIND_PORT% — SIP port, %TLS_BIND_PORT% — TLS SIP port, %NAT% — sets the public address in SIP headers, %TOS%, %COS%

; UDP transport behind NAT
[transport-udp-nat]
type=transport
