NAT SETTINGS

If the devices are kept within a private network behind a firewall, we recommend using STUN Server. The following settings

are useful in the STUN Server scenario:

STUN Server

Under Settings→General Settings, enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server

on the internet and enter it in this field. If using Public IP, keep this field blank.

Use Random Ports

It is under Settings→General Settings. This setting depends on your network settings. When set to "Yes", it will force random

generation of both the local SIP and RTP ports. This is usually necessary when multiple GRPs are behind the same NAT. If using

a Public IP address, set this parameter to "No".

NAT Traversal

It is under Accounts X→Network Settings. The default setting is "No". Enable the device to use NAT traversal when it is

behind a firewall on a private network. Select Keep-Alive, Auto, STUN (with STUN server path configured too), or other options

according to the network setting.

GRP260X is embedded with a packet capture function. The related options are under Maintenance→System

Diagnosis→Packet Capture.

Users can also define whether RTP packets will be captured or not from With RTP Packets option.

When the capture configuration is set, press the Start button to start packet capture. The Status will become RUNNING while

capturing, as shown in Figure 7: Packet Capture when running. Press the Stop button to end capture.

Press the Download button to download the capture file to your local PC. The capture file is in .pcap format.

If "Yes", Network Access Identiﬁer (NAI) is included as a device identity in the

location request sent to the Location Information Server (LIS)

A user can conﬁgure multiple emergency numbers separated with the delimiter

symbol ";".

If "Yes", E.911 INVITE message includes the "Geolocation-Routing" header with the

value "Yes"

If "Yes", E.911 INVITE message includes the "Priority" header with the value

"emergency"
