CHAPTER68 Configuration Parameters Reference
Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
â– [1] No if 6xx = Upon receipt of a 3xx response, the
device tries each contact, one by one, listed in the
Contact headers. However, if a 6xx Global Failure
response is received during this process (e.g., 600 Busy
Everywhere) the device does not try to redirect the call to
the next contact, and drops the call.
â– [2] Yes = Upon receipt of a 3xx response, the device
redirects the call to the first contact listed in the Contact
header. If the contact responds with a SIP response that
is defined in the Reasons for Tel-to-IP Alternative
Routing table, the device tries to redirect the call to the
next contact, and so on. If a contact responds with a
response that is not configured in the table, the device
does not try to redirect the call to the next contact, and
drops the call.
'Redundant Routing Mode'
configure voip > sip-
definition settings >
redundant-routing-m
[RedundantRoutingMode]
Determines the type of redundant routing mechanism when a
call can’t be completed using the main route.
â– [0] Disable = No redundant routing is used. If the call
can’t be completed using the main route (using the active
Proxy or the first matching rule in the Routing table), the
call is disconnected.
â– [1] Routing Table = (Default) Internal routing table is
used to locate a redundant route.
â– [2] Proxy = Proxy list is used to locate a redundant route.
Note: To implement the Redundant Routing Mode
mechanism, you first need to configure the parameter
AltRouteCauseTEL2IP (Reasons for Alternative Routing
table).
'Disconnect Call With PI If Alt'
[DisconnectCallwithPIifAlt]
Defines when the device sends the IP-to-Tel call to an
alternative route (if configured) when it receives an ISDN
Q.931 Disconnect message from the Tel side.
â– [0] Disable = (Default) The device forwards early media
to the IP side if Disconnect includes PI, and disconnects
the call when a Release message is received. Only after
the call is disconnected does the device send the call to
an alternative route.
â– [1] Enable = The device immediately sends the call to
the alternative route.
For more information, see Alternative Routing upon ISDN
Disconnect.
Note: The parameter is applicable only to digital interfaces.

tel-to-ip
[EnableAltMapTel2IP]
Enables different Tel-to-IP destination number manipulation
rules per routing rule when several (up to three) Tel-to-IP
routing rules are defined and if alternative routing using
release causes is used. For example, if an INVITE message
for a Tel-to-IP call is returned with a SIP 404 Not Found
response, the call can be re-sent to a different destination
number, configured by the [NumberMapTel2IP] parameter.
