RPORT
The Session Initiation Protocol (SIP) operates over UDP and TCP. When used with UDP,
responses to requests are returned to the source address from which the request came, and
returned to the port written into the topmost “Via” header of the request. However, this behavior
is not desirable when the client is behind a firewall.
A parameter created for the “Via” header called “
Rport
” in RFC 3581, allows a client to request
that the server send the response back to the source IP address
and
the port from which the
request came.
When you enable “Rport, the phone always uses symmetric signaling (listens on the port used
for sending requests).
An Administrator can configure “
Rport
” using the configuration files or the Mitel Web UI.
Configuring Rport Using the Configuration Files
Use the following procedures to configure Rport on your phone.
For specific parameters you can set in the configuration files, see Appendix A, the section,
“Rport Setting” on page A-30.
Note:
Configuring the Rport parameter is recommended for clients behind a firewall
since this parameter allows a client to request that the server send the response back
to the source IP address and the port from which the request came.
