User's Manual
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] 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.

[1] Enable = The device immediately sends the call to the
alternative route.
For more information, see Alternative Routing upon ISDN Disconnect
on page 502.
Note: The parameter is applicable only to digital interfaces.
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
Enables the device to automatically switch the destination of an FXS
call from the FXO (PSTN) to the IP (SIP Trunk) when the PSTN
disconnects the FXS subscriber.

[0] = (Default) Disable

[1] = Enable
For more information, see Alternative Routing from FXO to IP on
page 502.
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).
