NAT configuration commands
•
NAT_SIGNALLING NONE | SIPPING | STUN indicates the type of protocol used for NAT traversal in the signaling port. The IP Phone
1140E with SIP Firmware supports two methods of NAT traversal of the signaling path SIPPING and STUN NONE - If the value is not set to None, this parameter overrides the value of the parameter SIPPING in the device configuration file SIP_PING - a Nortel 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.
ATTENTION
NAT_TTL x is used for future development. Currently, the default value is 2 minutes (120 seconds) and SIP IP Phones 1120E/1140E do not processor use the value defined in NAT_TTL [x]. SIP IP Phones
1120E/1140E always ping the ports at regular intervals of 60 seconds regardless of the NAT_TTL value.
