Note: This feature is also applicable to 3xx redirect responses. The
device adds the prefix "T~&R-" to the URI user part in the Contact
header if the SBC3xxBehavior parameter is set to 1.

settings > sbc-3xx-bhvt
[SBC3xxBehavior]
Global parameter that defines the handling of SIP 3xx redirect
responses. You can also configure this feature per specific calls, using
IP Profiles (IpProfile_SBCRemote3xxBehavior). For a detailed
description of the parameter and for configuring this feature in the IP
Profiles table, see Configuring IP Profiles on page 404.
Note: If this feature is configured for a specific IP Profile, the settings of
this global parameter is ignored for calls associated with the IP Profile.
configure voip >
sbc settings >
enforce-media-
order
[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 the 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 the parameter is disabled, the only ‘m=’ line included in the SDP is
the newly negotiated media (i.e., image).
SBC Diversion URI Type
configure voip > sbc
settings > sbc-diversion-
uri-type
[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
Profiles table determine the call redirection (diversion) SIP header to
use - History-Info or Diversion.
SBC Server Auth Mode
configure voip > sbc
settings > 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.
Lifetime of the nonce in
seconds
configure voip > sbc
settings > lifetime-of-
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. The parameter is
used to provide replay protection (i.e., ensures that old communication
