Contents Introduction
xConfiguration H323 Profile [1..1] CallSetup Mode
The H.323 Call Setup Mode defines whether to use a Gatekeeper or Direct calling when establishing
H323 calls.
NOTE: Direct H.323 calls can be made even though the H.323 Call Setup Mode is set to
Gatekeeper.
Requires user role: ADMIN
Value space: <Direct/Gatekeeper>
Direct: An IP address must be used when dialing in order to make the H323 call.
Gatekeeper: The system will use a Gatekeeper to make a H.323 call. When selecting this option
the H323 Profile Gatekeeper Address and H323 Profile Gatekeeper Discovery settings must also
be configured.
Example: xConfiguration H323 Profile 1 CallSetup Mode: Gatekeeper
xConfiguration H323 Profile [1..1] 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
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.
Example: xConfiguration H323 Profile 1 Encryption MinKeySize: Max1024bit
xConfiguration H323 Profile [1..1] Gatekeeper Discovery
Determine how the system shall register to a H.323 Gatekeeper.
Requires user role: ADMIN
Value space: <Manual/Auto>
Manual: The system will use a specific Gatekeeper identified by the Gatekeeper's IP address.
Auto: The system will automatically try to register to any available Gatekeeper. If a Gatekeeper
responds to the request sent from the codec within 30 seconds this specific Gatekeeper will
be used. This requires that the Gatekeeper is in auto discovery mode as well. If no Gatekeeper
responds, the system will not use a Gatekeeper for making H.323 calls and hence an IP address
must be specified manually.
