Configuring Proxy Sets Table

The Proxy Sets Table page allows you to define Proxy Sets. A Proxy Set is a group of
Proxy servers defined by IP address or fully qualified domain name (FQDN). You can
define up to 32 Proxy Sets, each with a unique ID number and up to five Proxy server
addresses. For each Proxy server address you can define the transport type (i.e., UDP,
TCP, or TLS). In addition, Proxy load balancing and redundancy mechanisms can be
applied per Proxy Set (if a Proxy Set contains more than one Proxy address).
Proxy Sets can later be assigned to IP Groups of type SERVER (see ''Configuring IP
Groups'' on page 179). When the device sends an INVITE message to an IP Group, it is
sent to the IP address or domain name defined for the Proxy Set that is associated with the
IP Group. In other words, the Proxy Set represents the destination of the call. Typically,
for IP-to-IP call routing, at least two Proxy Sets are defined for call destination – one for
each leg (IP Group) of the call (i.e., both directions). For example, one Proxy Set for the
Internet Telephony Service provider (ITSP) interfacing with one 'leg' of the device and
another Proxy Set for the second SIP entity (e.g., ITSP) interfacing with the other 'leg' of
the device.
Notes:
SIP User's Manual
If configured, INVITE messages initiated from the IP Group are
sent to this Serving IP Group (range 1 to 9). In other words, the
INVITEs are sent to the address defined for the Proxy Set
associated with this Serving IP Group. The Request-URI host
name in the INVITE messages are set to the value of the 'SIP
Group Name' parameter defined for the Serving IP Group.
Notes:

This field is available only if the IP-to-IP application is
enabled.

If the parameter PreferRouteTable is set to 1, the routing
rules in the 'Outbound IP Routing Table' takes precedence
over this 'Serving IP Group ID' parameter.

If this parameter is not configured, the INVITE messages are
sent to the default Proxy or according to the 'Outbound IP
Routing Table'.
•
You can also configure the Proxy Sets table using two complementary ini
file table parameters (see ''Configuration Parameters Reference'' on
page 409):
- ProxyIP: used for creating a Proxy Set ID defined with IP addresses.
- ProxySet: used for defining various attributes for the Proxy Set ID.
•
Proxy Sets can be assigned only to SERVER-type IP Groups.
