Pvqmon Ip; Nat Traversal - Nortel 1120E Administration Manual

88 Device Settings on the IP Phone 1120E with SIP Firmware
Password
Enter the password used by the provisioning server for authentication of the
IP Phone 1120E with SIP Firmware.

PVQMon IP

If the Proactive Voice Quality Monitor (PVQMon) server is available on the
network, enter the PVQMon IP address.

NAT Traversal

The next five menu items apply to configuring the NAT Traversal Method if
the IP Phone 1120E with SIP Firmware is connected to the network through
a Network Address Translation device or a firewall.
NAT Signal
The IP Phone 1120E with SIP Firmware supports two methods of NAT
traversal of signaling path: SIP_PING and STUN.
The default NAT traversal method is None.
SIP_PING is a legacy Nortel Proprietary protocol for NAT Traversal for SIP
signaling only. STUN is an Internet standard for NAT traversal.
If the value for NAT traversal is not set to None, this parameter overrides
the value of the parameter SIP_PING specified by the device configuration
file for NAT_SIGNALLING.
If the value for NAT traversal is set to None, the value of SIP_PING, if
specified by the device configuration file for NAT_SIGNALLING, is used
instead.
NAT_SIGNALLING is required for networks that use STUN or SIP_PING
for NAT traversal.
NAT Media
The IP Phone 1120E with SIP Firmware supports STUN for media path
the NAT traversal. The NAT Media feature can be disabled by setting the
NAT_Media field in Device Settings menu to NONE.
NAT TTL
Enter the Time to Live (TTL) in seconds for the NATport if STUN is enabled.
The Nortel IP Phone 1120E with SIP Firmware pings the open ports on an
interval less than the TTL to prevent the NAT from tearing down the ports.

Note: STUN protocol cannot coexist with Application Layer Gateway
(ALG), Media Portals, or RTP Proxy servers. If STUN is selected,
ensure none of these devices are configured in the SIP Proxy server.
