Mediant 500 E-SBC
Parameter Description
[DisconnectCallwithPIifAlt] Defines when the device sends the IP-to-Tel call to an alternative
route (if configured) when it receives an ISDN Q.931 Disconnect
message from the Tel side.

[0] (Default) = The device forwards early media to the IP side if
Disconnect includes PI, and disconnects the call when a
Release message is received. Only after the call is disconnected
does the device send the call to an alternative route.

[1] = The device immediately sends the call to the alternative
route.
For more information, see Alternative Routing upon ISDN
Disconnect on page
408 .
[EnableAltMapTel2IP] 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

alt-route-cause-tel2ip
[AltRouteCauseTel2IP]
This table parameter 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 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 the ini file table 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)
For a detailed description of this table, see ''Alternative Routing
Based on SIP Responses'' on page

alt-route-cause-ip2tel
[AltRouteCauseIP2Tel]
This table parameter configures call failure reason values received
from the PSTN side (in Q.931 presentation). If a call is released as
a result of one of these reasons, the device attempts to locate an
alternative Trunk Group for the call in the Inbound IP Routing table.
The format of the ini file table parameter is as follows:
[AltRouteCauseIP2Tel]
FORMAT AltRouteCauseIP2Tel_Index =
AltRouteCauseIP2Tel_ReleaseCause;
[\AltRouteCauseIP2Tel]
For example:
AltRouteCauseIP2Tel 0 = 3 (No Route to Destination)
