Step 4
Set the fields as required.
Field Name
Description
Use gatekeeper
Enables/disables the use of a gatekeeper. If No is selected, all
the other fields are greyed. If Yes is selected, the Codec Unit can
use the gatekeeper’s services.
Automatic IP address
Automatic gatekeeper discovery. The Codec Unit searches for an
available gatekeeper.
IP address
Enter the IP address of the gatekeeper, if you do not use
Automatic IP address.
Use H.460
If set to Yes, the system uses H.460 firewall traversal features.
Auto registration
Automatic registration is used to discover whether the
registration state to the gatekeeper has been lost. Loosing
registration state could be very annoying as a gatekeeper call
will not reach the Codec Unit and the latter wouldn’t be aware
that it is unreachable. This option must be enabled only if the
gatekeeper sends the RAS Information Request messages (IRQ) at
periodic interval (e.g.: every 60 seconds). The Codec Unit replies
with the RAS Information Request Response messages (IRR), as
mandated by H.225.0.
Registration expiration time If the Codec Unit does not receive an IRQ for a time longer than
the Registration expiration time, it presumes that the
registration state in the gatekeeper has been lost (due to line
problem or gatekeeper crash).
Re-registration interval time Therefore the Codec Unit starts a new registration procedure,
repeating it upon failure at the Re-Registration Interval Time.
This value is used also for normal registration when it fails. This
field is useful if you do not want to use the normal RAS
lightweight registration procedure. This option is normally off
and must be enabled only it the Codec Unit administrator is sure
that the gatekeeper sends the IRQ messages. If not, the Codec
Unit unregisters and registers at every Registration expiration
Time.
Authentication
If Authentication is enabled, the related fields must be defined.
If it is not enabled, the four text fields (Mode, Gatek. ID, User
name, Password) are greyed.
Mode
Automatic, MD5, H.235 annex D - If set to Automatic, the
Codec Unit selects the best mode according to the gatekeeper.
Gatek. ID
Gatekeeper H.323 identifier. Ask the network administrator.
User name
The network administrator must pre-configure the User name in
the gatekeeper.
Password
The network administrator must pre-configure the Password in
the gatekeeper.
