SIP User's Manual
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 = 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.
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 = 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.
This parameter table configures the Proxy Set table with Proxy
Set IDs, each with up to five Proxy server IP addresses (or fully
qualified domain name/FQDN). Each Proxy Set can be defined
with a transport type (UDP, TCP, or TLS). The format of this
parameter is as follows:
[ProxyIP]
FORMAT ProxyIp_Index = ProxyIp_IpAddress,
ProxyIp_TransportType, ProxyIp_ProxySetId;
[\ProxyIP]
For example:
ProxyIp 0 = 10.33.37.77, -1, 0;
ProxyIp 1 = 10.8.8.10, 0, 2;
ProxyIp 2 = 10.5.6.7, -1, 1;
Notes:

This parameter can include up to 32 indices (0-31).

To assign various attributes (such as Proxy Load Balancing)
per Proxy Set ID, use the parameter ProxySet.

For configuring the Proxy Set ID table using the Web
interface and for a detailed description of the parameters of
this ini file table, see 'Configuring Proxy Sets Table' on page
