General Information - Nortel 1110 Fundamentals

NAT Traversal is applicable to all UNIStim IP Phone clients and is
one-ended. That is, it does not require the other end of a call to support any
special protocol, and it is interoperable with any other media termination.
In this document NAT refers to both IP port address mapping and IP
address mapping (also known as NAPT). A NAT is used with or without a
Virtual Private Network (VPN).
The NAT Traversal feature supports only IP clients behind cone NAT types.
Three types of cone NAT are: full cone, restricted cone, and port restricted
cone. NAT traversal is not compatible with symmetric NATs. If the IP Phone
is behind a Symmetric NAT, the LTPS unregisters the phone from the call
server (while remaining registered on the LTPS), and displays the following
message on the IP Phone display: Error! Symmetric NAT.
For detailed information about the NAT Traversal feature, see IP Line
Fundamentals (NN43100-500).
For information about accessing NAT information from an IP Phone, see
"Set IP Information" (page
Nortel recommends partial DHCP configuration for IP Phones residing behind
a NAT router unless the NAT router supports special configuration of the DHCP
server. For more information, see IP Line Fundamentals (NN43100-500).
