Business environment. The device sends a special SRV query to
the DNS server according to the transport protocol configured in
the 'Transport Type' parameter (described later in this section):

TLS: "_sipinternaltls_tcp.<domain>" and "_sip_tls.<domain>".
For example, if the configured domain name (in the 'Proxy
Address' parameter) is "ms-server.com", the device queries
for "_sipinternaltls_tcp.ms-server.com" and "_sip_tls.ms-
server.com".

TCP: "_sipinternal._tcp.<domain>" and "_sip_tcp.<domain>".

Undefined: "_sipinternaltls_tcp.<domain>",
"_sipinternal_tcp.<domain>", "_sip_tls.<domain>" and
"_sip_tcp.<domain>".
The SRV query returns the host names (and their weights). The
device then performs DNS A-record queries per host name
(according to the received weights) to resolve into IP addresses.
Note: An SRV query can return up to four host names. For each host
name, the subsequent DNS A-record query can resolve into up to 15
IP addresses. However, the device supports up to 30 DNS-resolved
IP addresses. If the device receives more than this number of IP
addresses, it uses the first 30 IP addresses in the received list and
ignores the rest.
Defines an index number for the new table row.
Note: Each row must be configured with a unique index.
Defines the address of the proxy.
Up to 10 addresses can be configured per Proxy Set. The address
can be defined as an IP address in dotted-decimal notation (e.g.,
201.10.8.1) or FQDN. You can also specify the port using the
following format:

IPv4 address: <IP address>:<port> (e.g., 201.10.8.1:5060)

IPv6 address: <[IPV6 address]>:<port> (e.g.,
[2000::1:200:200:86:14]:5060)
Note:

When configured with an FQDN, you can configure the periodic
rate at which the device performs DNS queries to resolve the
FQDN into IP addresses. For more information, see the
ProxyIPListRefreshTime parameter.

When configured with an FQDN, you can configure the method
(e.g., A-record) for resolving the domain name into an IP address,
using the 'DNS Resolve Method' parameter in this table (see
above).

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 configure the device to use the port indicated in the
Request-URI of the incoming message, instead of the port
configured for the parameter. To enable this, use the
IPGroup_SBCRouteUsingRequestURIPort parameter for the IP
Group that is associated with the Proxy Set (Configuring IP
