NAT configuration commands
• NAT_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 - an 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:
NAT_TTL [x] is used for future development. Currently, the default value is 2
minutes (120 seconds) and IP Deskphones do 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 Server IP addresses can be
provisioned.
- — ip_address - is the IP address of STUN Server 2.
• STUN_SERVER_PORT1[port_number] — the port number used corresponding to
STUN_SERVER_IP1. The default port number is 3478.
- — port_number - is the port number.
• STUN_SERVER_PORT2[port_number] — the port number used corresponding to
STUN_SERVER_IP2. The default port number is 3478.
- — port_number - is the port number.
