Valid Range and Description
FilterCalls2IP
[Filter Calls To IP]
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.
Alternative Routing Parameters
AltRoutingTel2IPEnable
[Enable Alt Routing Tel to IP]
Operation modes of the Alternative Routing mechanism:
0 = Disabled (default).
1 = Enabled.
2 = Enabled for status only, not for routing decisions.
AltRoutingTel2IPMode
[Alt Routing Tel to IP Mode]
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
8.6 on page 146 .
