Network Address Translation (NAT)

NAT enables phones with private unregistered addresses to communicate with devices with globally unique
registered addresses.

NAT Traversal Configuration
The phones can traverse NAT gateways to establish and maintain connections with external devices.
Yealink phones support three NAT traversal techniques: manual NAT, STUN and ICE. If you enable manual NAT
and STUN, the phone will use the manually-configured external IP address for NAT traversal. The TURN protocol is
used as part of the ICE approach to NAT traversal.
The following table lists the parameters you can use to configure NAT traversal.
Parameter account.X.nat.nat_traversal
It enables or disables the NAT traversal for a specific account.
Description
Note: If it is set to 1 (STUN), it works only if "static.sip.nat_stun.enable" is set to 1 (Enabled); if it is set
to 2 (Manual NAT), it works only if "static.network.static_nat.enable" is set to 1 (Enabled).
0-Disabled

Parameter static.network.static_nat.addr
It configures the IP address to be advertised in SIP signaling.
