Mediant 500 E-SBC
Parameter Description
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.
