• Security: H.235 128-bit AES security in H.323 calls. When enabled, the system automatically encrypts calls to other systems that have
AES encryption enabled. When set to AES, calls connect, are encrypted only if the far end supports AES encryption. If the far end user
does not support AES encryption, calls are not encrypted.
• Use Gatekeeper: Set to On when you use the gatekeeper function. This unit supports the H.460 protocol for firewall and NAT traversal
of H.323 calls. You must have an H.460 server configured in your environment for this feature to function properly. If you set to On, the
H.460 NAT, Gatekeeper Address and Gatekeeper Port options are enabled to set it.
• H.460 NAT: Set to On when you use the H.460 standard for NAT and firewall traversal.
• GateKeeper Address: Enter the IP address of the primary H.323 gatekeeper.
• GateKeeper Port: Enter the port number of the primary H.323 gatekeeper.
