Parameter Description
'Additional UDP Ports'
additional-udp-ports
[SIPInterface_AdditionalUDPPorts]
Defines a port range for the device's local, listening
and source ports for SIP signaling traffic over UDP.
The parameter can be used for the following features:
■ 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 on page459.
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
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.
