54.10.11 IP Connectivity Parameters
The IP connectivity parameters are described in the table below.
Table 54-58: IP Connectivity Parameters
Parameter Description
Web: Enable Alt Routing Tel to IP
EMS: Enable Alternative Routing
CLI: alt-routing-tel2ip
[AltRoutingTel2IPEnable]
Enables the Alternative Routing feature for Tel-to-IP calls.

[0] Disable = (Default) Disables the Alternative Routing
feature.

[1] Enable = Enables the Alternative Routing feature.

[2] Status Only = The Alternative Routing feature is
disabled, but read-only information on the QoS of the
destination IP addresses is provided.
Web: Alt Routing Tel to IP Mode
EMS: Alternative Routing Mode
CLI: alt-rte-tel2ip-mode
[AltRoutingTel2IPMode]
Determines the IP Connectivity event(s) reason for triggering
Alternative Routing.

[0] None = Alternative routing is not used.

[1] Connectivity = Alternative routing is performed if SIP
OPTIONS message to the initial destination fails
(determined according to the AltRoutingTel2IPConnMethod
parameter).

[2] QoS = Alternative routing is performed if poor QoS is
detected.

[3] Both = (Default) Alternative routing is performed if either
SIP OPTIONS to initial destination fails, poor QoS is
detected, or the DNS host name is not resolved.
Notes:

QoS is quantified according to delay and packet loss
calculated according to previous calls. QoS statistics are
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
627 ) 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
CLI: alt-rte-tel2ip-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.
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
[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 [%]
CLI: mx-pkt-loss-4-alt-rte Defines the packet loss (in percentage) at which the IP
connection is considered a failure and Alternative Routing
mechanism is activated.
