NAT configuration commands

• NA

T_SIGNALLING [NONE | SIP_PING | STUN] — indicates the type of protocol used

for NAT traversal in the signaling port. The IP Deskphone with SIP Software supports two

methods of NAT traversal of the signaling path: SIP_PING and STUN.

- NONE - If the value is not configured as None, this parameter overrides the value

of the parameter SIP_PING in the device configuration file.

- SIP_PING - a Avaya proprietary NAT traversal protocol. Note that SIP_PING only

supports NAT traversal in the signaling port.

- STUN - the most common NAT traversal method.

• NAT_MEDIA [NONE | STUN] — indicates the type of protocol used for NAT traversal in

the media ports. The default is NONE.

- NONE - is the default and disables NAT_MEDIA.

- STUN - the most common NAT traversal protocol for the media (RTP and Real-time

Control Protocol [RTCP]) port.

- x - is the binding lifetime in seconds.

Important:

T_TTL [x] is used for future development. Currently, the default value is 2

minutes (120 seconds) and IP Deskphone does not process or use the value

defined in NAT_TTL [x]. The IP Deskphone always pings the ports at regular

intervals of 60 seconds regardless of the NAT_TTL value.

• STUN_SERVER_IP1[ip_address] — NAT traversal using STUN protocol requires a

STUN server in the public internet. Two STUN server IP addresses can be provisioned.

- ip_address - is the IP address of STUN server 1.

• STUN_SERVER IP2[ip_address] — NAT traversal using STUN protocol requires a

STUN server in the public internet. Two STUN servers IP addresses can be

provisioned.

- ip_address - is the IP address of STUN server 2.
