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.
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 a ping or 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 ping or
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 587) per
destination, this 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.
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.
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%.
