Version 7.2 1195 Mediant 500 MSBR
User's Manual 74. Configuration Parameters Reference
configure voip > gateway
manipulation settings > alt-
map-tel-to-ip
[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
[TR104FXOSwitchover] Enables the device to automatically switch the destination of an FXS
call from the FXO (PSTN) to the IP (SIP Trunk) when the PSTN
disconnects the FXS subscriber.

[0] = (Default) Disable

[1] = Enable
For more information, see Alternative Routing from FXO to IP on
page 522.
Alternative Routing Tone
Duration
configure voip > gateway
routing settings > 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).
Note:

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 514).
Reasons for Alternative Tel-to-IP Routing Table
Reasons for Alternative
Routing
configure voip > gateway
routing alt-route-cause-
tel2ip
[AltRouteCauseTel2IP]
Defines 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 Tel-to-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 more information, see Alternative Routing Based on SIP
Responses on page 514.
