destination number (as defined using the parameter
NumberMapTel2IP).
[0] = Disable (default)
[1] = Enable
Web/EMS: Alternative
Routing Tone Duration [ms]
[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: This parameter is applicable only to Tel-to-IP alternative
routing.

[AltRouteCauseTel2IP]
This table parameter configures SIP call failure reason values
these reasons, the device attempts to locate an alternative IP route
for the call in the Tel to IP Routing (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 this 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)

Based on SIP Responses' on page 235.

Tel
[AltRouteCauseIP2Tel]
This table parameter configures call failure reason values received
from the Tel side . If a call is released as a result of one of these
reasons, the device attempts to locate an alternative Hunt Group for
the call in the IP to Hunt Group Routing Table.
The format of this parameter is as follows:
[AltRouteCauseIP2Tel]
FORMAT AltRouteCauseIP2Tel_Index =
AltRouteCauseIP2Tel_ReleaseCause;
[\AltRouteCauseIP2Tel]
For example:
AltRouteCauseIP2Tel 0 = 3 (No Route to Destination)
AltRouteCauseIP2Tel 1 = 1 (Unallocated Number)
AltRouteCauseIP2Tel 2 = 17 (Busy Here)
AltRouteCauseIP2Tel 2 = 27 (Destination Out of Order)
Note: For a detailed description of this table, see 'Alternative Routing
to Trunk upon Q.931 Call Release Cause Code' on page 237.
