reset if no new data is received within two minutes.
To receive quality information (displayed in the 'Quality
Status' and 'Quality Info.' fields in 'Viewing IP Connectivity'
on page 371) per destination, this parameter must be set to
2 or 3.
Web: Alt Routing Tel to IP
Connectivity Method
EMS: Alternative Routing
Telephone to IP Connection
Method
[AltRoutingTel2IPConnMethod]
Determines the method used by the device for periodically
querying the connectivity status of a destination IP address.
[0] ICMP Ping = (Default) Internet Control Message Protocol
(ICMP) ping messages.
[1] SIP OPTIONS = The remote destination is considered
offline if the latest OPTIONS transaction timed out. Any
response to an OPTIONS request, even if indicating an
error, brings the connectivity status to online.
Web: Alt Routing Tel to IP Keep
Alive Time
EMS: Alternative Routing Keep
Alive Time
[AltRoutingTel2IPKeepAliveTime]
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 [%]
[IPConnQoSMaxAllowedPL]
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]
[IPConnQoSMaxAllowedDelay]
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.
43.10.12 Alternative Routing Parameters
The alternative routing parameters are described in the table below.
Table 43-59: Alternative Routing Parameters
Parameter Description
Web/EMS: Redundant
Routing Mode
[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.
[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).
[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
