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 on 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 GXPs 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. Default setting is "No". Enable the device to use NAT
traversal when it is behind firewall on a private network. Select Keep-Alive, Auto, STUN (with STUN
server path configured too) or other option according to the network setting.
MULTICAST PAGING
GXP110x supports multicast paging listening. On the phone, users could send multicast page by setting
the multicast address and port. Also, users can listen to at most 10 different multicast IP address.
Receive Multicast Paging
To receive multicast page, GXP110x must be well configured to listen to the right address and port. The
configurations are under Settings->Multicast Paging. There are 10 listening address supported with
priority levels 1 to 10. Optionally, each of these addresses can also have a label that will display on LCD
when the page is received.
Note: The multicast page configuration requires rebooting to take effect.
