GLV-540 User Manual
40
For example:
GLV is in a private network such as home or office LAN and needs to initiate
and receive calls to / from other IP phones connected to the public internet.
o
IP Sharing: - In this method of NAT Traversal, a shared IP Address
(typically the router or NAT WAN IP address) is configured at GLV.
This IP Address is used as the public IP Address in all the call signaling.
Note
:
The local RTP media ports selected are assumed to be mapped one to
one on the public side and their selection is controlled through the
configurable RTP port range.
o
STUN: - This NAT Traversal method facilitates detecting the type of
NAT and the binding (public IP address & port) corresponding to the
local IP Address and port. In comparison to IP Sharing method where
the public IP address is statically configured, STUN detects the public
IP address dynamically on the fly.
STUN NAT Traversal method requires the following parameters to be
configured:
STUN Server (Primary)
STUN Server (Secondary)
Note:
Currently STUN server address field expects IP Address as
input, domain name is not supported.
Please clear (set the field blank) the STUN parameters
Username & Password as most STUN servers do not accept or
require authentication for STUN messages.

Remote Monitoring using SIP Trace
SIP Trace feature facilitates viewing SIP signaling messages sent and received
by GLV through the Web Interface.
To view SIP Trace messages through the Web interface, Enable SIP Trace
option in “Debug Configuration”. Access “Device Monitor->SIP Trace” link to
view the SIP Trace messages through the Web Browser.
Note:
An option “Save to PC” is provided to facilitate saving the SIP Trace messages
displayed on the Web to a file. This can be used to provide a file containing
SIP signaling message while reporting issues to customer support.
5.1.22
Remote Monitoring using syslog
GLV supports remote device monitoring using syslog. The syslog messages
can be logged to a remote syslog server or logged locally for viewing through
the Web interface.
The following syslog parameters are configurable:
o
“Debug Mode”: This specifies the interface to log syslog messages
o
"Debug Level”: This controls the verbosity of the syslog debug
messages
o
“Syslog Server Address”: Address and Port of remote syslog server
