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] This parameter indicates the type of protocol
used for NA
T 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 the 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.
STUN_SERVER_PORT1[port_number] This parameter is the port number used
