Version 6.8 619 Mediant 2600 E-SBC
User's Manual 43. Configuration Parameters Reference
Parameter Description
Note: If this functionality is configured for a specific IP Profile, the
settings of this global parameter is ignored for calls associated with
the IP Profile.
[SBCEnforceMediaOrder]
Enables the device to include all previously negotiated media lines
within the current session ('m=' line) in the SDP offer-answer
exchange (RFC 3264).
[0] Disable (default)
[1] Enable
For example, assume a call (audio) has been established between
two endpoints and one endpoint wants to subsequently send an
image in the same call session. If this parameter is enabled, the
endpoint includes the previously negotiated media type (i.e., audio)
with the new negotiated media type (i.e., image) in its SDP offer:
v=0
o=bob 2890844730 2890844731 IN IP4
host.example.com
s=
c=IN IP4 host.example.com
t=0 0
m=audio 0 RTP/AVP 0
m=image 12345 udptl t38
If this parameter is disabled, the only ‘m=’ line included in the SDP
is the newly negotiated media (i.e., image).
Web: SBC Diversion URI Type
CLI: sbc-diversion-uri-type
(configure voip > sbc general-
setting)
[SBCDiversionUriType]
Defines the URI type to use in the SIP Diversion header of the
outgoing SIP message.
[0]
Transparent = (Default) The device does not change the URI
and leaves it as is.
[1] Sip = The "sip" URI is used.
[2] Tel = The "tel" URI is used.
Note: The parameter is applicable only if the Diversion header is
used. The SBCDiversionMode and SBCHistoryInfoMode
parameters in the IP Profile table determine the call redirection
(diversion) SIP header to use - History-Info or Diversion.
Web: SBC Server Auth Mode
CLI: sbc-server-auth-mode
[SBCServerAuthMode]
Defines whether authentication of the SIP client is done locally (by
the device) or by a RADIUS server.
[0] (default) = Authentication is done by the device (locally).
[1] = Authentication is done by the RFC 5090 compliant
RADIUS server
[2] = Authentication is done according to the Draft Sterman-aaa-
sip-01 method.
Note: Currently, option [1] is not supported.
Web: Lifetime of the nonce in
seconds
CLI: lifetime-of-nonce
[AuthNonceDuration]
Defines the lifetime (in seconds) that the current nonce is valid for
server-based authentication. The device challenges a message
that attempts to use a server nonce beyond this period. This
parameter is used to provide replay protection (i.e., ensures that
old communication streams are not used in replay attacks).
The valid value range is 30 to 600. The default is 300.
Web: Authentication Challenge
Method
CLI: auth-chlng-mthd
Defines the type of server-based authentication challenge.
[0] 0 = (Default) Send SIP 401 "Unauthorized" with a WWW-
Authenticate header as the authentication challenge response.
