AudioCodes Mediant 500L MSBR

User's Manual 67. Configuration Parameters Reference
Version 6.8 995 Mediant 500L MSBR
Parameter Description
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 427.
[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
Web/EMS: Alternative Routing
Tone Duration [ms]
CLI: alt-rte-tone-duration
[AltRoutingToneDuration]
Defines the duration (in milliseconds) for which the device plays a
tone to the endpoint on each attempt for Tel-to-IP alternative
routing. When the device finishes playing the tone, a new SIP
INVITE message is sent to the new IP destination. The tone played
is the call forward tone (Tone Type #25 in the CPT file).
The valid range is 0 to 20,000. The default is 0 (i.e., no tone is
played).
Notes:
 The parameter is applicable only to FXS or FXO interfaces.
 The parameter is applicable only to Tel-to-IP alternative routing
based on SIP responses (see Alternative Routing Based on SIP
Responses on page 420).

manipulations general-setting
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 420.
Reasons for Alternative IP-to-Tel Routing Table
Web: Reasons for Alternative
IP-to-Tel Routing
EMS: Alt Route Cause IP to Tel
CLI: configure voip > gw
This table parameter configures call failure reason values received
from the Tel 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.
