User's Manual

[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.

[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.
Determines the type of redundant routing mechanism when a call
can't be completed using the main route.

[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.

[1] Routing Table = (Default) Internal routing table is used to
locate a redundant route.

[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).
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.

[0] (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.

[1] = The device immediately sends the call to the alternative
route.
For more information, see Alternative Routing upon ISDN
Disconnect on page 406.
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 (as defined using the parameter
NumberMapTel2IP).

[0] = Disable (default)

[1] = Enable
