To configure the IP Handset do as follows:
1. Make a SIP profile using the SIP account details SIP server, user name and
password. For instructions see To add a new SIP profile on page 77.
2. Select SIP from the main menu, then select the new SIP profile you want to
use for communication.
3. Select Connect. The handset registers itself, and you are ready to make a
secure call.
Typically you make the call and then go into secure mode by selecting Go
secure in the menu Main options. You can go into secure mode anytime
during a call. When using the IP Handset in networks where all calls must be
secure, you can set the handset to start a secure session automatically each
time when a call is initiated and the peer IP Handset goes off-hook. For further
details see To set call services (Noise cancellation and Automatic secure) on
page 70.

Description
Please refer to the manufacturer's documentation.
The configuration of the IP connection of the BGAN
terminal determines the speech quality of the
IP Handset. The following two examples show a high-
quality and a best-effort quality.
•
Secure connection with guaranteed high speech
quality: Start a Streaming data session at 64 kbps.
The IP Handset is by default configured to G.711 codec
(64 kbit).
•
Secure connection with best-effort speech quality:
Start a Standard data session. In this case set the
codec priority in the SIP profile of the IP Handset to
G.729. For details see To edit a SIP profile on
page 80.
