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.

Parameter
sip.tls_listen_port
<y0000000000xx>.cfg
Description

If it is set to 0, the phone will not listen to the TLS service.
Permitted
Values

VPN
Yealink phones use OpenVPN to achieve VPN feature. To prevent disclosure of private information, tunnel end-
points must authenticate each other before a secure VPN tunnel is established. After you configure VPN feature on
the IP phone, the phone will act as a VPN client and use the certificates to authenticate with the VPN server.

OpenVPN Related Files
To use OpenVPN, you should collect the VPN-related files into one archive file in .tar format and then upload this tar
file. The VPN-related files include certificates (ca.crt and client.crt), key (client.key) and the configuration file
(vpn.cnf) of the VPN client.
The following table lists the unified directories of the OpenVPN certificates and key in the configuration file (vpn.cnf)
for Yealink phones:
