Mediant 500L MSBR
Parameter Description
[0] Disable = (Default) The device replaces the original
Contact user with a unique Contact user, for example:
Received Contact: <sip:123@domain.com>
Outgoing (unique) Contact: <sip:FEU1_7_1@SBC>
[1] Enable = The original Contact user is retained and used in
the outgoing REGISTER request.
Note: This parameter is applicable only to REGISTER messages
received from User-type IP Groups and that are sent to Server-
type IP Groups.
Web: SBC Remote Refer
Behavior
CLI: sbc-refer-bhvr
[SBCReferBehavior]
Global parameter that defines the handling of SIP REFER
requests. You can also configure this functionality per specific
calls, using IP Profiles (IpProfile_SBCRemoteReferBehavior). For
a detailed description of this parameter and for configuring this
functionality in the IP Profile table, see ''Configuring IP Profiles''
on page 332.
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.
CLI: sbc-xfer-prefix
[SBCXferPrefix]
When the SBCReferBehavior is set to 1, the device, while
interworking the SIP REFER message, adds the prefix "T~&R-
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.
CLI: sbc-3xx-bhvt
[SBC3xxBehavior]
Global parameter that defines the handling of SIP 3xx redirect
responses. You can also configure this functionality per specific
calls, using IP Profiles (IpProfile_SBCRemote3xxBehavior). For a
detailed description of this parameter and for configuring this
functionality in the IP Profile table, see ''Configuring IP Profiles''
on page 332.
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-
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:
