Configuring Proxy Sets

The Proxy Sets table lets you configure up to 100 Proxy Sets. A Proxy Set defines the
destination address (IP address or FQDN) and transport type (e.g., UDP) of a SIP server
(e.g., Proxy). Each Proxy Set can be configured with up to 10 addresses configured as an
IP address and/or DNS host name (FQDN), enabling you to implement load balancing and
redundancy between multiple servers. If you configure the address as an FQDN, you can
configure the method (A-record DNS, SRV, or NAPTR) for resolving the domain name to
an IP address. The device supports up to 30 DNS-resolved IP addresses. (If the DNS
resolution provides more than this number, the device uses the first 30 IP addresses in the
received list, and ignores the rest.)
You can assign each Proxy Set with a specific SSL/TLS certificate (TLS Context), enabling
the use of different certificates per SIP entity (IP Group).
Proxy Sets are later assigned to Server-type IP Groups, in the IP Group table. When the
device sends an INVITE message to an IP Group, it sends it to the address configured for
the Proxy Set. You can also enable the classification of incoming SBC SIP dialogs to IP
Groups based on Proxy Set. If the source address of the incoming SIP dialog is the same
as the address of a Proxy Set that is assigned to an IP Group, the device classifies the SIP
User's Manual
according to the Classification table.

If the configured SIP header does not exist in the incoming
INVITE message, the classification of the message to a source IP
Group fails.

If the device receives an INVITE as a result of a REFER request
or a 3xx response, the incoming INVITE is routed according to
the Request-URI. The device identifies such INVITEs according
to a specific prefix in the Request-URI header, configured by the
SBCXferPrefix parameter. Therefore, in this scenario, the device
ignores this parameter setting.
Defines the shared username for authenticating the IP Group, when
the device acts as an Authentication server.
The valid value is a string of up to 51 characters. By default, no
username is defined.
Notes:

This parameter is applicable only to Server-type IP Groups and
when the 'Authentication Mode' parameter is set to SBC as
Server (i.e., authentication of servers).

To specify the SIP request types (e.g., INVITE) that must be
challenged by the device, use the 'Authentication Method List'
parameter.
Defines the shared password for authenticating the IP Group, when
the device acts as an Authentication server.
The valid value is a string of up to 51 characters. By default, no
password is defined.
Notes:

This parameter is applicable only to Server-type IP Groups and
when the 'Authentication Mode' parameter is set to SBC as
Server (i.e., authentication of servers).

To specify the SIP request types (e.g., INVITE) that must be
