CHAPTER 60 Configuration Parameters Reference
Mediant 4000 SBC | User's Manual
Parameter Description
■ [1] keep user without unique
identifier = The device retains the
original user part value of the Contact
header in the outgoing REGISTER
request.
■ [2] Keep user; add unique identifier
as URI parameter = The device retains
the original user part value of the
Contact header in the outgoing
REGISTER request. In addition, it adds
the special URI parameter "ac-
feu=<identifier>" to the Contact header,
which is used to differentiate between
two SIP entities with the same user
part. The identifier value is generated by
the device.
✔
Incoming Contact Header:
<sip:123@domain.com>
✔
Outgoing Contact Header:
<sip:123@SBC;ac-feu=1-7-1-3>
Note:
■ The parameter is applicable only to
REGISTER messages received from
User-type IP Groups which are sent to
Server-type IP Groups.
■ Depending on the 'Remote
Representation Mode' parameter of the
IP Profiles table (IpProfile_
SBCRemoteRepresentationMode), the
host part in the SIP Contact header can
replaced by the device’s IP address or
by the value of the 'SIP Group Name'
parameter (configured in the IP Groups
table).
'URI Comparison Excluded Parameters'
config-voip > sbc settings > uri-
comparison-excluded-params
[SBCURIComparisonExcludedParams]
Defines which URI parameters are
excluded when the device compares the
URIs of two incoming dialog-initiating SIP
requests (e.g., INVITEs) to determine if
they were sent from a user that is registered
in the device's registration database
(registered AOR and corresponding Contact
URI), during Classification.
The value of the parameter is a free-text
string, which cannot be empty. You can
configure it to any sequence of parameters,
separated by commas (e.g., "transport,
maddr, ttl"). Alternatively, you can configure
it to one of the following values (case-
insensitive):
- 973 -
