3.4.5.1.3 Proxy Sets Table
The 'Proxy Sets Table' page allows you to define up to six groups of logical IP addresses
(i.e., Proxy Sets), each containing up to five Proxy server IP addresses or FQDN's. In
addition, Proxy load balancing and redundancy mechanisms can be applied per Proxy Set
(if a Proxy Set contains more than one Proxy).
The Proxy Set ID can later be assigned to an IP Group (refer to ''Configuring the IP
Groups'' on page 231). When the device sends an INVITE message to an IP Group, it is
sent to the IP address of the Proxy Set associated with the specific IP Group.
Note:
Version 5.4
Determines the mode for Challenge Caching, which reduces the number of
SIP messages transmitted through the network. The first request to the Proxy
is sent without authorization. The Proxy sends a 401/407 response with a
challenge. This response is saved for further uses. A new request is resent
with the appropriate credentials. Subsequent requests to the Proxy are
automatically sent with credentials (calculated from the saved challenge). If
the Proxy doesn't accept the new request and sends another challenge, the
old challenge is replaced with the new one.
[0] None = Challenges are not cached. Every new request is sent without
preliminary authorization. If the request is challenged, a new request with
authorization data is sent (default)
[1] INVITE Only = Challenges issued for INVITE requests are cached.
This prevents a mixture of REGISTER and INVITE authorizations.
[2] Full = Caches all challenges from the proxies.
Note: Challenge Caching is used with all proxies and not only with the active
one.
Determines the device's mode of operation when Authentication and Key
Agreement (AKA) Digest Authentication is used.
[0] Optional = Incoming requests that don't include AKA authentication
information are accepted (default).
[1] Mandatory = Incoming requests that don't include AKA authentication
information are rejected.
You can also configure the Proxy Sets table using the ini file table parameters
ProxyIP and ProxySet (refer to ''SIP Configuration Parameters'' on page 323).
