5.5.3. Establishing an IP communication in DIRECT SIP mode.
•
Ensure that the equipment is powered up.
•
Check that the RJ45 cable is correctly connected and secured.
•
Check that the amber indicator lamp in the communications module is blinking regularly.
•
Verify the status of the communications interface. Ensure that no error message
appears in the MAIN STATUS menu screen for this communications module.
•
Establish the appropriate audio configuration (analog / digital input mode, gains, routing
of inputs to the codec, suitable encoding, analog output modes).
•
Set the VU meters at the most suitable adjustment point and check the input audio.
•
Go into the interface configuration and select the “DIRECT SIP” mode. Then press the
“ADVANCED” context key. There you will be able to select the unit name in “USER” and
the physical interface for audio in “AUDIO”. Select the NAT resolver working mode
(“NAT TRAVERSAL”) depending on the connection of the unit.
NOTE: We recommend you to follow the application notes 0-A or 0-C (depending on the
connection of the unit).
•
Assign the IP logic interface to the channel.
•
Press the CALL button associated with the communications channel that is going to
use the IP interface as the connection base; this action will open the connection
configuration menu. Basically, it is a question at this point of ensuring that all the fields
are correct, and that they correspond to what you have configured previously:
o
Check that the assigned IP interface is the desired one.
o
Select the encoding profile to be used in the communication. There are several
established profiles, each of which contains one or more particular encodings,
in order of preference. More profiles can be edited and added.
o
Select the working mode and the reception buffer size (see paragraph 4.4 of
this manual in order to select the optimal buffer configuration depending on
your application).
o
You have the possibility of using the backup option, with its corresponding
configuration submenu in BACK UP:
Activate or not the backup option.
Select the interface to use as a backup.
Select the encoding mode. Make sure that the mode you select is
compatible with the communications interface selected, especially as
regards the associated bit rates.
Define the minimum time interval for the connection to be considered
down and the communication interface switching to be performed.
Select the number of retries to be made before considering the
communication down.
Define the minimum time interval for the connection to be considered
down if synchronization is not performed, and for the communication
interface switching to be performed.
Define the destination toward which the backup connection is to be
launched. Depending on the communication interface you have
selected as a backup, this destination will be defined by an ISDN
subscriber number, a SIP identifier (URI) or an IP address.
o
Enter the identifier of the contact to be called, either manually or from the
internal phone book in CALL BOOK. Enter the IP identifier in the following
format:
<unit_name>@<unit_IP_address>
(for
instance,
[email protected]). VERY IMPORTANT: <unit_name> must be no
longer than 19 characters.
•
Press the CALL button on the front panel again, or select the DIAL option on screen, to
make the call.
If you select the number to call from the phone book, you can perform the same action
by using the contextual button associated with the DIAL option.
•
You can monitor the status of the call on the OLED screen:
o
CALLING.
o
CONNECTING (depending on the communication interface, this may be an
extremely brief status).
