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.) Each Proxy
Set can be assigned a specific SSL/TLS certificate the (TLS Context), enabling you to use
different TLS certificates per SIP entity (IP Group). In addition, each Proxy Set must be
assigned a SIP Interface (and SRD), which determines, amongst others, the device's local
network interface through which communication with the Proxy Set is done.
To use a configured Proxy Set, you need to assign it to an IP Group in the IP Group table
(see ''Configuring IP Groups'' on page 343). When the device sends INVITE messages to
an IP Group, it sends it to the address configured for the Proxy Set. You can assign the
same Proxy Set to multiple IP Groups (belonging to the same SRD).
You can also enable the device to classify 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, the device classifies the SIP dialog as belonging to the IP Group that is
associated with the Proxy Set.
Notes:
•
It is recommended to classify incoming SIP dialogs to IP Groups, based on the
Classification table (see Configuring Classification Rules on page 595) instead of
based on Proxy Set.
•
You can view the device's connectivity status with proxy servers in the Tel-to-IP
Routing table, for Tel-to-IP routing rules whose destination is an IP Group that is
associated with a Proxy Set. The status is only displayed for Proxy Sets enabled
with the Proxy Keep-Alive feature.
The Proxy Set is configured using two tables, one a "child" of the other:

Proxy Sets table: Defines the attributes of the Proxy Set such as associated SIP
Interface and redundancy features - ini file parameter, ProxySet

Proxy Set Address table ("child"): Defines the addresses of the Proxy Set - table ini
file parameter, ProxyIP

To configure a Proxy Set:
1. Open the Proxy Sets table (Configuration tab > VoIP menu > VoIP Network > Proxy
Sets Table).
