Mediant 800 Gateway & E-SBC | User's Manual
Description
■ [1] Enable = The device assigns a unique local port for
each Account for which the device initiates registration.
The port is taken from a configured UDP port range.
The port range is configured for the SIP Interface
('Additional UDP Ports' parameter - SIPInterface_
AdditionalUDPPorts) associated with the Proxy Set of
the Account's Serving IP Group. Traffic between the
Serving IP Group and device is sent from and received
on the assigned unique local port. If enabled for other
Accounts that are configured with the same Serving IP
Group, each Account is allocated a unique UDP port
from the port range. For example, if you have configured
two Accounts, "PBX-1" and "PBX-2", the device could
assign port 6000 to "PBX-1" and 6100 to "PBX-2".
Note:
■ The parameter is applicable only to the SBC
application.
■ If you enable the parameter, you must also enable the
device to initiate registration for the Account (i.e.,
configure the 'Register' parameter to any value other
than No).
■ If the device fails to allocate a port (e.g., insufficient
ports), the device does not send the SIP REGISTER
request, but tries again within a period configured by the
RegistrationRetryTime and
MaxRegistrationBackoffTime parameters.
■ If the device receives a SIP request from the Serving IP
Group for the Account, on a port that was not assigned
to the Account, it rejects the request (with a SIP 404
Not Found response).
■ If the device receives a SIP request from the Served IP
Group and the Account has not been allocated a valid
port, the device rejects the request (with a SIP 500
Server Internal Error response).
■ For more information on configuring the SIP Interface's
port range, see Configuring SIP Interfaces
