88Device Settings on the IP Phone E with SIP Firmware
PVQMon IPIf the Proactive Voice Quality Monitor (PVQMon) server is available on the network, enter the PVQMon IP address.
NAT TraversalThe next five menu items apply to configuring the NAT Traversal Method if the IP Phone E with SIP Firmware is connected to the network through a Network Address Translation device or a firewall.
NAT SignalThe IP Phone E with SIP Firmware supports two methods of NAT traversal of signaling path SIPPING and STUN.
The default NAT traversal method is None.
SIP_PING is a legacy Nortel Proprietary protocol
for NAT Traversal for SIPsignaling 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 SIPPING specified by the device configuration file for NAT_SIGNALLING.
If the value for NAT traversal is set to None, the value of SIPPING, 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 MediaThe IP Phone E 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.
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.
NAT TTLEnter the Time to Live (TTL) in seconds for the NATport if STUN
is enabled. The Nortel IP Phone E with SIP Firmware pings the open ports on an interval less than the TTL to prevent the NAT from tearing down the ports.
STUN SIP bEnter an IP address for the STUNS IP device. The STUN
server must reside in the public Internet for STUN protocol to be effective.
STUN SIP bEnter an IP address for the STUNS IP device. The STUN
server must reside in the public Internet for STUN protocol to be effective.
