SIP User's Manual
Parameter
Web/EMS: Challenge Caching
Mode
[SIPChallengeCachingMode]
Web: Proxy IP Table
EMS: Proxy IP
[ProxyIP]
Version 5.8
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.
This ini file table parameter configures the Proxy Set table for
configuring up to six 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 30 indices (0-29).

The Proxy Set represents the destination of the call.

For assigning various attributes (such as Proxy Load
Balancing) per Proxy Set ID, use the ini
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, refer to ''Configuring the Proxy Sets Table''
on page 103 .
