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: Max1024bit/Min1024bit/Min2048bit
Max1024bit: The maximum size is 1024 bit.
Min1024bit: The minimum 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 device, 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 device 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 H323 NAT Mode is intended to be used if your device is on a private network and is not
registered to a gatekeeper. H323 NAT Mode can then be used to reach devices on a public
network.
NAT is not supported for IPv6.
NOTE: The H323 NAT Mode and H323 NAT Address settings will be ignored if the
video conferencing devices is registered to a gatekeeper. We recommend the use of a
gatekeeper with firewall traversal capabilities, rather than using the H323 NAT Mode.
Requires user role: ADMIN
Default value: Off
Value space: Auto/Off/On
Auto: Auto mode works only if you have specified the NAT address in the H323 NAT
Address setting.
NAT is turned On if the device is not registered to a gatekeeper, the local address of the
device is private, the address you are calling (remote) is public, and both the local and
remote addresses are IPv4. Otherwise, NAT is turned Off.
This means that you can place calls to devices on your private network as well as to
external devices (outside your private network). For calls on your private network, the
H323 NAT Address is not used (but must be present). For calls to the public network, the
H323 NAT Address is used.
Off: NAT is turned off, and the H323 NAT Address setting will be ignored. In this case
you will not be able to set up a call to a device that is outside of your private network
unless you use a gatekeeper.
On: NAT is always turned on. You must specify the NAT address in the H323 NAT
Address setting. The device will always signal the H323 NAT Address instead of its
private IP address in Q.931 and H.245. If the H323 NAT Address is wrong or not set,
H.323 calls cannot be set up.
