Cisco DX70 and DX80
Introduction

H323 Encryption KeySize

Define the minimum or maximum key size for the Diffie-Hellman key exchange method,
which is used when establishing the Advanced Encryption Standard (AES) encryption key.
Requires user role: ADMIN
Default value: Min1024bit
Value space: Min1024bit/Max1024bit/Min2048bit
Min1024bit: The minimum size is 1024 bit.
Max1024bit: The maximum size is 1024 bit.
Min2048bit: The minimum size is 2048 bit.

H323 Gatekeeper Address

Define the IP address of the Gatekeeper. Requires H323 CallSetup Mode to be set to
Gatekeeper.
Requires user role: ADMIN
Default value: ""
Value space: String (0, 255)
A valid IPv4 address, IPv6 address or DNS name.

H323 H323Alias E164

The H.323 Alias E.164 defines the address of the system, according to the numbering plan
implemented in the H.323 Gatekeeper. The E.164 alias is equivalent to a telephone number,
sometimes combined with access codes.
Requires user role: ADMIN
Default value: ""
Value space: String (0, 30)
The H.323 Alias E.164 address. Valid characters are 0-9, * and #.

H323 H323Alias ID

Define the H.323 Alias ID, which is used to address the system on a H.323 Gatekeeper and
will be displayed in the call lists.
Requires user role: ADMIN
Default value: ""
Value space: String (0, 49)
The H.323 Alias ID. Example: "firstname.lastname@company.com", "My H.323 Alias ID"

H323 NAT Mode

The firewall traversal technology creates a secure path through the firewall barrier, and
enables proper exchange of audio/video data when connected to an external video
conferencing system (when the IP traffic goes through a NAT router). NOTE: NAT does not
work in conjunction with gatekeepers.
Requires user role: ADMIN
Default value: Off
Value space: Auto/Off/On
Auto: The system will determine if the H323 NAT Address or the real IP address should
be used in signaling. This makes it possible to place calls to endpoints on the LAN as
well as endpoints on the WAN. If the H323 NAT Address is wrong or not set, the real IP
address will be used.
Off: The system will signal the real IP address.
On: The system will signal the configured H323 NAT Address instead of its real IP
address in Q.931 and H.245. The NAT server address will be shown in the startup-menu
as: "My IP Address: 10.0.2.1". If the H323 NAT Address is wrong or not set, H.323 calls
cannot be set up.
