Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
■ [0] Disable = (Default) Sends the
INVITE only to the contact of the
received Request-URI.
■ [1] Enable
To configure call forking initiated by the
device, see Initiating SIP Call Forking.
'SBC Shared Line Registration Mode'
configure voip > sbc settings >
sbc-shared-line-reg-mode
[SBCSharedLineRegMode]
Enables the termination on the device of
SIP REGISTER messages from secondary
lines that belong to the Shared Line feature.
■ [0] Disable = (Default) Device forwards
the REGISTER messages as is (i.e.,
not terminated on the device).
■ [1] Enable = REGISTER messages of
secondary lines are terminated on the
device.
Note: The device always forwards
REGISTER messages of the primary line.
'SBC Forking Handling Mode'
configure voip > sbc settings >
sbc-forking-handling-mode
[SBCForkingHandlingMode]
Defines the handling of SIP 18x responses
that are received due to call forking of an
INVITE.
■ [0] Latch On First = (Default) Only the
first 18x is forwarded to the INVITE-
initiating UA. If SIP 18x with SDP is
received, the device opens a voice
stream according to the received SDP
and disregards any subsequent 18x
forking responses (with or without
SDP). If the first response is 180
without SDP, the device sends it to the
other side.
■ [1] Sequential = All 18x responses are
forwarded, one at a time (sequentially)
to the INVITE-initiating UA. If a 18x
arrives with an offer only, then only the
first offer is forwarded to the INVITE-
initiating UA and subsequent 18x
responses are discarded.
'Gateway Direct Route Prefix'
configure voip > sbc settings >
gw-direct-route-prefix
[GWDirectRoutePrefix]
Defines the prefix destination Request-URI
user part that is appended to the original
user part for alternative IP-to-IP call routing
from SBC to Gateway (Tel) interfaces.
The valid value is a string of up to 16
characters. The default is "acgateway-
<original prefix destination number>". For
example, "acgateway-200".

IP-to-IP Routing Rules.
