9. Move to the setting you want to change
and select Edit. Type in the information
and enter with OK .
• User name: When connecting to a
BGAN terminal, the user name should
be the same as the local number for
the handset.
• Password: When connecting to a
BGAN terminal, the password must
match the IP Handset password
entered in the terminal.
• Codec priority: Select the codec type that should have the highest
priority. You may select G.711 or G.729 A/B.
• STUN server : If your SIP telephony installation requires a STUN server
name, you can enter it here. Refer to the documentation of the SIP
server.
• Reregister every : This settings sets the time interval in which the
IP Handset registers with the SIP server it is connected to. If the SIP
server is the BGAN terminal, you don’t need to change this setting. The
interval is set to 120 seconds (default). The maximum value is 86400
seconds (24 hours).
If the connection to an external SIP provider is made through a NAT
router, this setting may be needed to keep the connection through NAT
to the SIP server open. This setting should in this case typically be set
to 20 seconds.

Note
If the IP Handset registers with the SIP server over a satellite
connection or other telecommunications network you may set
this time interval to a larger value to avoid unintended use of
bandwidth.
