SIP User's Manual
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.
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 example, if an INVITE message for a Tel-
to-IP call is returned with a SIP 404 Not Found response, the
call can be re-sent to a different destination number (as defined
using the parameter NumberMapTel2IP).

[0] = Disable (default)

[1] = Enable
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 value 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 value 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 value is 250.
This parameter table configures SIP call failure reason values
received from the IP side. If an IP call is released as a result of
one of these reasons, the device attempts to locate an
alternative IP route (address) for the call in the Outbound IP
Routing Table' (if a Proxy is not used) or used as a redundant
Proxy (you need to set the parameter RedundantRoutingMode
to 2). The release reason for Tel-to-IP calls is provided in SIP
4xx, 5xx, and 6xx response codes.
The format of this parameter is as follows:
[AltRouteCauseTel2IP]
FORMAT AltRouteCauseTel2IP_Index =
AltRouteCauseTel2IP_ReleaseCause;
[\AltRouteCauseTel2IP]
For example:
AltRouteCauseTel2IP 0 = 486; (Busy Here)
AltRouteCauseTel2IP 1 = 480; (Temporarily Unavailable)
AltRouteCauseTel2IP 2 = 408; (No Response)
Notes:

This parameter can include up to 5 indices.

The reasons for alternative routing for Tel-to-IP calls apply
