Conference [1..1] Encryption Mode: <Off/BestEffort>
BestEffort: The system will use encryption whenever possible.
In Point to point calls: If the far end system supports encryption (AES-128), the call will be encrypted. If not,
the call will proceed without encryption.
In MultiSite calls: In order to have encrypted MultiSite conferences, all sites must support encryption. If not,
the conference will be unencrypted.
Icons on screen: A padlock with the text “Encryption On” displays on screen, for a few seconds, when the
conference starts.
Off: The system will not use encryption.
Example: Conference 1 Encryption Mode: BestEffort
Conference [1..1] DefaultCall Protocol: <H323/SIP>
Specify the Default Call Protocol to be used when placing calls from the system. The call protocol can also
be defined directly for each call when setting up a call.
H.323: Select H.323 to ensure that calls are set up as a H.323 calls.
SIP: Select SIP to ensure that calls are set up as a SIP calls.
Example: Conference 1 DefaultCall Protocol: H323
Conference [1..1] DefaultCall Rate: <64..6000>
Specify the Default Call Rate to be used when placing calls from the system. The call rate can also be
defined directly for each call when setting up a call.
Range: 64-6000 kbps
Example: Conference 1 DefaultCall Rate: 766
H323 Profile [1..1] PortAllocation: <Dynamic/Static>
The H.323 Port Allocation setting affects the H.245 port numbers used for H.323 call signalling.
Dynamic: The system will allocate which ports to use when opening a TCP connection. The reason for doing
this is to avoid using the same ports for subsequent calls, as some firewalls consider this as a sign of attack.
When Dynamic is selected, the H.323 ports used are from 11000 to 20999. Once 20999 is reached they
restart again at 11000. For RTP and RTCP media data, the system is using UDP ports in the range 2326 to
2487. Each media channel is using two adjacent ports, ie 2330 and 2331 for RTP and RTCP respectively.
The ports are automatically selected by the system within the given range. Firewall administrators should not
try to deduce which ports are used when, as the allocation schema within the mentioned range may change
without any further notice.
Static: When set to Static the ports are given within a static predefined range [5555–6555].
Example: H323 Profile 1 PortAllocation: Dynamic
H323 Profile [1..1] H323Alias ID: <S: 0, 49>
Lets you specify 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. Example: “name.surname@company.com”, “My H.323 Alias ID”
Format: String with a maximum of 49 characters
Example: H323 Profile 1 H323Alias ID: “”
H323 Profile [1..1] H323Alias E164: <S: 0, 30>
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. Example: “9047615901”, “”550092”
Format: Compact string with a maximum of 30 characters. Valid characters are 0–9, * and #.
Example: H323 Profile 1 H323Alias E164: “”
H323 Profile [1..1] CallSetup Mode: <Direct/Gatekeeper>
The H.323 Call Setup Mode defines whether to use a Gatekeeper or Direct calling when establishing H323
calls.
Direct: An IP-address must be used when dialling 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.
NOTE! Direct H.323 calls can be made even though the H.323 Call Setup Mode is set to Gatekeeper.
Example: H323 Profile 1 CallSetup Mode: Gatekeeper
H323 Profile [1..1] Gatekeeper Address: <S: 0, 64>
Specifies the IP address of the Gatekeeper. Requires the H.323 Call Setup Mode to be set to Gatekeeper
and the Gatekeeper Discovery to be set to Manual.
Format: String with a maximum of 64 characters.
Example: H323 Profile 1 Gatekeeper Address: “10.47.1.58”
The Do not disturb setting
DoNotDisturb Mode: <On/Off>
The Do Not Disturb setting determines whether or not there should be an alert on incoming calls.
On: Set to On when you want no alert to incoming calls. The calling side will receive a busy signal when
trying to call the codec.
Off: This is the default setting. The DoNotDisturb is automatically turned Off if the codec receives any IR
signal from the handheld remote control.
Example: DoNotDisturb Mode: Off
