Parameter Description
■ Assigning a specific local port to each SIP entity
(e.g., PBX) communicating with a common SIP
entity (e.g., proxy server). This is the port on the
leg interfacing with the proxy server. In other
words, the SIP Interface associated with the
proxy server. For more information, see
Configuring Specific UDP Ports using Tag-based
Routing.
■ Assigning a unique port for each Account
registering with the same Serving IP Group
(registrar server). For more information, see
Configuring Registration Accounts on page435.
The valid range is 1,025 to 65535. The range is
configured using the syntax x-y, where x is the
starting port and y the ending port of the range (e.g.,
6000-7000). By default, the parameter is not
configured.
Note:
■ To configure whether the device keeps the
configured ports (sockets) open or opens them
only when needed, use the SIP Interface's
'Additional UDP Ports Mode' parameter (below).
■ The parameter's port range value must not
overlap with the UDP port configured by the 'UDP
Port' parameter (SIPInterface_UDPPort). For
example, if the 'UDP Port' parameter is
configured to 5070, you cannot configure the
'Additional UDP Ports' parameter with a range of
5060-6000.
■ The parameter's port range value must not
overlap with UDP port ranges of Media Realms
and Media Realm Extensions that are configured
on the same network interface. For example, if
the RTP port range is 6000-6999, you must
configure the 'Additional UDP Ports' parameter to
a range that is less than 6000 or greater than
6999.
■ The maximum number of ports in the range is
limited to the maximum number of licensed
registered SBC users as specified in the License
Key installed on the device, or the maximum
number of IP Groups that can be configured (see
Configuring IP Groups) - the higher of the two
determines it. For example, if the License Key
allows 20 users and the maximum IP Groups that
can be configured is 10, then the maximum
number of ports is 20.
