Table 72-70: IP Connectivity Parameters
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.
Note: If the parameter is enabled, the Busy Out feature (see
EnableBusyOut parameter) does not function with the Proxy Set
keep-alive mechanism. To use the Busy Out feature with the
Proxy Set keep-alive mechanism (for IP Groups), disable the
parameter.
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.
Note:

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
951) per destination, the parameter must be set to 2 or 3.
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.
