Parameter Description
■ All = (Default) All URI parameters
(except the gruu parameter "gr" and
AudioCodes proprietary parameter "ac-
int") and ports are excluded in the
comparison of the two URIs. Therefore,
if there are two different registrations of
the same user whose Contacts are
differentiated only by ports and/or a
proprietary parameter, the device
considers them to be the same single
registration, even though they are
different registrations.
■ None = All URI parameters and ports
are included in the comparison of the
two URIs.
■ Port = The ports of the URIs are
excluded in the comparison of the two
URIs, but all other URI parameters are
included in the comparison. "port" can
be combined with other URI parameters
that you want excluded (e.g., port,
transport, proprietary-param).
For example, if two SIP requests are
received with different Contact header
values, as shown below (in bold) and the
parameter is configured to All, then the
device considers these requests as
received from the same registered user as it
disregards the port (5060 and 5070),
'transport', and 'tt'l parameters in its
comparison. If configured to None, the
device considers these requests as
received from two different registered
users.
