Contents Introduction
xConfiguration H323 Profile [1..1] 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
Value space: <S: 0, 30>
Format: Compact string with a maximum of 30 characters. Valid characters are 0-9, * and #.
Example: xConfiguration H323 Profile 1 H323Alias E164: "90550092"
xConfiguration H323 Profile [1..1] H323Alias ID
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: "firstname.lastname@company.com", "My H.323 Alias
ID"
Requires user role: ADMIN
Value space: <S: 0, 49>
Format: String with a maximum of 49 characters.
Example: xConfiguration H323 Profile 1 H323Alias ID: "firstname.lastname@company.com"
xConfiguration H323 Profile [1..1] PortAllocation
The H.323 Port Allocation setting affects the H.245 port numbers used for H.323 call signalling.
Requires user role: ADMIN
Value space: <Dynamic/Static>
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: xConfiguration H323 Profile 1 PortAllocation: Dynamic
