Rport Configuration

Rport allows a client to request that the server sends the response back to the source IP address and port from
which the request originated. It helps the phone traverse symmetric NATs.
Rport feature depends on support from a SIP server. For more information, refer to
The following table lists the parameter you can use to configure rport.
Parameter account.X.nat.rport
Description It enables or disables the phone to add the "rport" parameter in the Via header.
0-Disabled
1-Enabled, the INVITE Contact header uses the port in the "rport" parameter but does not use the
Permitted
source IP address in the "received" parameter in the Via header of server's response.
Values
2-Enable Direct Process, the INVITE Contact header uses the port in the "rport" parameter and uses
the source IP address in the "received" parameter in the Via header of server's response.

SIP Port and TLS Port Configuration

You can configure the SIP and TLS source ports on the phone. Otherwise, the phone uses default values (5060 for
UDP/TCP and 5061 for TLS).
If NAT is disabled, the port number shows in the Via and Contact SIP headers of SIP messages. If NAT is enabled,
the phone uses the NAT port number (and NAT IP address) in the Via and Contact SIP headers of SIP messages,
but still using the configured source port.
The following table lists the parameters you can use to configure SIP port and TLS port.
Parameter sip.listen_port
It specifies the local SIP port.
Description
If it is set to 0, the phone will automatically listen to the local SIP port.
Permitted
0, Integer from 1024 to 65535
Values
Default 5060
Web UI Settings > SIP > Local SIP Port
Parameter sip.tls_listen_port
It specifies the local TLS listen port.
Description
If it is set to 0, the phone will not listen to the TLS service.
Permitted
0, Integer from 1024 to 65535
Values
