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 <y0000000000xx>.cfg
Description
It specifies the local SIP port.
If it is set to 0, the phone will automatically listen to the local SIP port.
Permitted
