SIP Port and TLS Port Configuration
You can configure the SIP and TLS source ports on the IP Phone. Otherwise, the IP 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 configures the local SIP port.
Permitted Values Integer from 1024 to 65535

Parameter sip.tls_listen_port <y0000000000xx>.cfg

If it is set to 0, the IP phone will not listen to the TLS service.
Permitted Values 0, Integer from 1024 to 65535
