CHAPTER 60 Configuration Parameters Reference
Mediant 4000 SBC | User's Manual
Parameter Description
Note: The AudioCodes proprietary "feu"
string value for the user part must be
included in the Contact header of
REGISTER requests that the device
forwards to the registrar server when the
parameter is configured to a non-default
value (i.e., not
All ). Therefore, if you
configure the parameter to a non-default
value, the
SBCKeepContactUserInRegister
parameter must not be configured to
Keep
User Without Unique Identifier (1).
'SBC REFER Behavior'
configure voip > sbc settings >
sbc-refer-bhvr
[SBCReferBehavior]
Global parameter that defines the handling
of SIP REFER requests. You can also
configure this feature per specific calls,
using IP Profiles (IpProfile_
SBCRemoteReferBehavior). For a detailed
description of the parameter and for
configuring this feature in the IP Profiles
table, see
Configuring IP Profiles .
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 >
sbc-xfer-prefix
[SBCXferPrefix]
When the SBCReferBehavior is set to 1,
the device, while interworking the SIP
REFER message, adds the prefix "T~&R-"
to the user part of the URI in the Refer-To
header. After this, the device can receive an
INVITE with such a prefix (the INVITE is
sent by the UA that receives the REFER
message or 302 response). If the device
receives an INVITE with such a prefix, it
replaces the prefix with the value defined for
the SBCXferPrefix parameter.
By default, no value is defined.
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.
configure voip > sbc 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 .
