Parameter
■ [1] IP Address, Port & Transport Type = Classifies calls to
the Proxy Set according to IP address, port, and transport type.
Note:
■ The parameter is applicable only if the IP Groups table's
parameter 'Classify by Proxy Set' is set to Enable (see
Configuring IP Groups).
■ If multiple Proxy Sets are configured with the same IP address
and associated with the same SIP Interface, the device may
classify the SIP dialog (based on Proxy Set) to an incorrect IP
Group. In such a scenario, the device uses the Proxy Set with
the lowest Index number (e.g., Proxy Set ID #1 over Proxy Set
ID #4). A Syslog warning message is generated in such
scenarios. Therefore, it is recommended to configure each
Proxy Set with a unique IP address.
If multiple Proxy Sets are configured with the same IP address
but associated with different SIP Interfaces, then classification
based on Proxy Set can be correctly achieved.
If multiple Proxy Sets are configured with the same IP address
and SIP Interface, but with different ports (e.g., 10.1.1.1:5060
and 10.1.1.1:5070) and the parameter is configured to IP
Address, Port & Transport Type, classification to the correct
IP Group is achieved. Therefore, when classification is by
Proxy Set, pay attention to the configured IP addresses and
this parameter. When multiple Proxy Sets are configured with
the same IP address, the device selects the matching Proxy
Set in the following order:
✔
Selects the Proxy Set whose IP address, port, and
transport type match the source of the incoming SIP
request (regardless of the settings of this parameter).
✔
If no match is found for above, it selects the Proxy Set
whose IP address and transport type match the source of
the incoming SIP request (if the parameter is configured to
IP Address Only).
✔
If no match is found for above, it selects the Proxy Set
whose IP address match the source of the incoming SIP
request (if the parameter is configured to IP Address
Only).
For example:
Index Classification Input
IP Address, Port & Transport
1
Type
2 IP Address only
3 IP Address only
4 IP Address only
✔
Incoming SIP request from 10.10.10.10:5060;UDP:
Best match is #1 and #2 (same priority); second best
match is #3 (due to transport type); third best match is #4.
