9.10.15.3 Area: Security

No Security, Reduced Security, Full Security

Activation of the H.235 security protocol is configured here:

– No security: The security protocol is not used. No crypto tokens are sent by the IP

clients.

– Reduced security: The IP clients send crypto tokens and the HG 1500 verifies these

tokens. However, the HG 1500 itself does not send any crypto tokens.

– Full security: Both sides send and verify crypto tokens.

Identity

The global gatekeeper identity is specified here.

Password (only for trunking) / Confirm password

Enter the password here and confirm it by repeating the entry.

Security time

This setting configures monitoring for the lifetime of IP packets. This means that a check is then

performed in the communication system to ensure that the incoming IP packets are not older

than the current time plus the time specified in the Security time field. This prevents IP packets

from being potentially traced by a sniffer, for example, and then being resent to the original ad-

dressee after manipulation. The size of the Security time depends on the dynamic runtimes in

the customer LAN. If the selected time is too small, and long runtimes occur, disruptions may

occur in the VoIP traffic. A value of 90 seconds should work without problems in most cases.

In order to ensure that H.235 operates correctly, whenever any changes are made

to the corresponding parameters (Gatekeeper and Security), the individual compo-

nents must be restarted.
