Table 5-9: Proxy & Registration Parameters
Parameter Description
Challenge Caching
Mode
[SIPChallengeCachin
gMode]
Determines the mode used for Challenge Caching. Challenge Caching is
used to reduce 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 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.
Valid options include:
ƒ
[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)
ƒ
[1]
INVITE Only = Challenges are issued for INVITE requests are
cached. This prevents a mixture of REGISTER and INVITE
authorizations.
ƒ
[2]
Full = Cache all challenges from the proxies.
Note
: Challenge Caching is used with all proxies and not only with the active
one.
Mutual Authentication
Mode
[MutualAuthentication
Mode]
Determines the gateway's mode of operation when Authentication and Key
Agreement (AKA) Digest Authentication is used.
Valid options include:
ƒ
[0]
Optional = Incoming requests that don't include AKA authentication
information are accepted.
ƒ
[1]
Mandatory = Incoming requests that don't include AKA authentication
information are rejected.
5.5.1.3 Coders
The
Coders
option allows you to configure the first to fifth preferred coders (and their
attributes) for the gateway. The first coder is the highest priority coder and is used by the
gateway whenever possible. If the far-end gateway cannot use the coder assigned as the
first coder, the gateway attempts to use the next coder and so forth.
You can also configure the Coders table using the
ini
file parameter CoderName (refer to
'SIP Configuration Parameters' on page 279 ).
