SBC
Remote Re-

Support
Enum
NotSupported,Supported
Instant Determines whether the
destination of the re-INVITE
request supports re-INVITE
messages and if so, whether it
supports re-INVITE with or
without SDP.
[0] Not Supported = re-
INVITE is not supported.
[1] Supported with SDP = re-
INVITE is supported, but
only with SDP. If the re-
INVITE arrives without SDP,
the E-SBC creates an SDP
and adds it to the re-INVITE.
[2] Supported = (Default) re-
INVITE is supported with or
without SDP.

ed
Instant There are sip trunks that don't
support RE-INVITE or UPDATE
or both.
In case the SBC receives a RE-
INVITE or UPDATE requests, it
will always try to forward the
request to the remote side,
depending on the remote side
support. If it can't forward the
request as is, it can convert the
request or add SDP if
necessary, but if the remote
side doesn't support both RE-
INVITE and UPDATE it handles
the request locally.
The converted event
(request/response) will contain
all the headers of the original
message, except the URI and
Cseq headers that have to be
compatible to the method.
