Web Parameter Name
Valid Range and Description
AltRouteCauseTel2IP
Table of SIP call failure reason values received from the IP side. If a call
is released as a result of one of these reasons, the gateway tries to find
an alternative route to that call in the 'Tel to IP Routing' table (if Proxy is
not used) or used as a redundant Proxy (when Proxy is used).
Format for this ini file parameter table:
[AltRouteCauseTel2IP]
FORMAT AltRouteCauseTel2IP_Index =
AltRouteCauseTel2IP_ReleaseCause;
[\AltRouteCauseTel2IP]
For example:
[AltRouteCauseTel2IP]
AltRouteCauseTel2IP 0 = 486; (Busy here)
AltRouteCauseTel2IP 1 = 480; (Temporarily unavailable)
AltRouteCauseTel2IP 2 = 408; (No response)
[\AltRouteCauseTel2IP]
Notes:
 For an explanation on ini file parameter tables, refer to 'Structure of
ini File Parameter Tables' on page 269.
 The 408 reason can be used to specify no response from the remote
party to the INVITE request.
 This parameter can appear up to 5 times.

Embedded Web Server, refer to 'Reasons for Alternative Routing' on
page 130.
