the latest OPTIONS transaction timed out. Any response to an
OPTIONS request, even if indicating an error, brings the
connectivity status to online.
Note: ICMP Ping is currently not supported for the IP Connectivity
feature.
Web: Alt Routing Tel to IP
Keep Alive Time
EMS: Alternative Routing
Keep Alive Time
CLI: alt-rte-tel2ip-keep-
alive
[AltRoutingTel2IPKeepAli
veTime]
Defines the time interval (in seconds) between SIP OPTIONS Keep-
Alive messages used for the IP Connectivity application.
The valid range is 5 to 2,000,000. The default is 60.
Web: Max Allowed Packet
Loss for Alt Routing [%]
CLI: mx-pkt-loss-4-alt-rte
[IPConnQoSMaxAllowed
PL]
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%.
Web: Max Allowed Delay
for Alt Routing [msec]
CLI: mx-all-dly-4-alt-rte
[IPConnQoSMaxAllowed
Delay]
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.
66.11.14 Alternative Routing Parameters
The alternative routing parameters are described in the table below.
Alternative Routing Parameters
Parameter Description
Web/EMS: Redundant
Routing Mode
CLI: redundant-routing-m
[RedundantRoutingMode
]
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.
ï‚§ [1] Routing Table = (Default) Internal routing table is used to
locate a redundant route.
ï‚§ [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).
[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 (as defined using the parameter
NumberMapTel2IP).
ï‚§ [0] = Disable (default)
