0 = Disabled (default)
1 = Enabled
If the filter calls to IP feature is enabled, then when a Proxy is used, the gateway first
checks the Tel IP routing table before making a call through the Proxy. If the
number is not allowed (number isn't listed or a Call Restriction routing rule,
IP=0.0.0.0, is applied), the call is released.
Operation modes of the Alternative Routing mechanism:
0 = Disabled (default).
1 = Enabled.
2 = Enabled for status only, not for routing decisions.
0 (None) = Alternative routing is not used.
1 (Conn) = Alternative routing is performed if ping to initial destination failed.
2 (QoS) = Alternative routing is performed if poor quality of service was detected.
3 (All) = Alternative routing is performed if, either ping to initial destination failed, or
poor quality of service was detected, or DNS host name is not resolved (default).
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 for two minutes.
For information on the Alternative Routing feature, refer to Section
Packet loss percentage at which the IP connection is considered a failure.
The range is 1% to 20%. The default value is 20%.
Transmission delay (in msec) at which the IP connection is considered a failure.
The range is 100 to 1000. The default value is 250 msec.
