Parameter
Mediant 800 Gateway & E-SBC | User's Manual
Description
■ Assigning a unique port per registered user (User-
type IP Group) on the leg interfacing with the
proxy server (Server-type IP Group). For enabling
this feature and for more information, see the
'User UDP Port Assignment' parameter in the IP
Groups table.
■ 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
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:
■ The parameter is applicable only to the SBC
application.
■ 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.
