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.
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%.
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.
Table 67-71: Alternative Routing Parameters
Defines the handling of received SIP 3xx responses regarding call
redirection to listed contacts in the Contact header.

[0] No = (Default) Upon receipt of a 3xx response, the device
tries each contact, one by one, listed in the Contact headers,
until a successful destination is found. However, if a contact
responds with a 486 or 600, the device does not try to redirect
the call to next contact, and drops the call.

[1] No if 6xx = Upon receipt of a 3xx response, the device tries
each contact, one by one, listed in the Contact headers.
However, if a 6xx Global Failure response is received during this
process (e.g., 600 Busy Everywhere) the device does not try to
redirect the call to the next contact, and drops the call.

[2] Yes = Upon receipt of a 3xx response, the device redirects
the call to the first contact listed in the Contact header. If the
contact responds with a SIP response that is defined in the
Reasons for Tel-to-IP Alternative Routing table, the device tries
to redirect the call to the next contact, and so on. If a contact
responds with a response that is not configured in the table, the
device does not try to redirect the call to the next contact, and
