User's Manual
Defines the packet loss (in percentage) at which the IP
connection is considered a failure and Alternative Routing
mechanism is activated.
The default is 20%.
Defines the transmission delay (in msec) at which the IP
connection is considered a failure and the Alternative Routing
mechanism is activated.
The range is 100 to 10,000. The default is 250.
Table ‎ 5 1-66: Alternative Routing Parameters
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).
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
Defines the duration (in milliseconds) for which the device plays a
tone to the endpoint on each attempt for Tel-to-IP alternative routing.
When the device finishes playing the tone, a new SIP INVITE
message is sent to the new IP destination. The tone played is the call
forward tone (Tone Type #25 in the CPT file).
The valid range is 0 to 20,000. The default is 0 (i.e., no tone is
played).
Note: This parameter is applicable only to Tel-to-IP alternative
routing.
This table parameter configures SIP call failure reason values
received from the IP side. If an IP call is released as a result of one of
these reasons, the device attempts to locate an alternative IP route
