Description
■ [0] Do not keep user; override with
unique identifier = (Default) The
device replaces the user part of the
Contact header with a unique value, for
example:
✔
Incoming Contact Header:
<sip:123@domain.com>
✔
Outgoing Contact Header:
<sip:FEU1-7-1-3@SBC>
■ [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).
