Defines the Cnonce string used by the SIP server and client to
provide mutual authentication.
The value is free format, i.e., 'Cnonce = 0a4f113b'. The default
is 'Default_Cnonce'.
Determines the device's mode of operation when
Authentication and Key Agreement (AKA) Digest
Authentication is used.

[0] Optional = (Default) Incoming requests that don't include
AKA authentication information are accepted.

[1] Mandatory = Incoming requests that don't include AKA
authentication information are rejected.
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 re-sent
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 = (Default) 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.

[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.
Notes:

This parameter is applicable only to the Gateway
application.

Challenge Caching is used with all proxies and not only with
the active one.
This table parameter defines the Proxy Set table with Proxy
Set IDs, each with up to 10 Proxy server IP addresses (or
FQDN).
The format of the ini file table parameter is as follows:
[ProxyIP]
FORMAT ProxyIp_Index = ProxyIp_IpAddress,
ProxyIp_TransportType, ProxyIp_ProxySetId;
[\ProxyIP]
For a description of this table, see ''Configuring Proxy Sets'' on
page 296.
To configure the Proxy Set attributes (such as Proxy Load
Balancing) in the ini file, use the ProxySet parameter.
This table parameter defines the Proxy Set ID table. This
includes, for example, Proxy keep-alive and load balancing and
