Reasons for Alternative IP-
to-Tel Routing
configure voip > gateway
routing alt-route-cause-
ip2tel
[AltRouteCauseIP2Tel]
Defines 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 IP-to-Tel 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)
AltRouteCauseIP2Tel 1 = 1 (Unallocated Number)
AltRouteCauseIP2Tel 2 = 17 (Busy Here)
AltRouteCauseIP2Tel 2 = 27 (Destination Out of Order)
For more information, see Alternative Routing to Trunk upon Q.931
Call Release Cause Code on page 518.
Forward On Busy Trunk Destination Table
Forward On Busy Trunk
Destination
configure voip > gateway
routing fwd-on-bsy-trk-dest
[ForwardOnBusyTrunkDest
]
Defines the Forward On Busy Trunk Destination table. This table
allows you to define an alternative IP destination if a trunk is busy for
IP-to-Tel calls.
The format of the ini file table parameter is as follows:
[ForwardOnBusyTrunkDest]
FORMAT ForwardOnBusyTrunkDest_Index =
ForwardOnBusyTrunkDest_TrunkGroupId,
ForwardOnBusyTrunkDest_ForwardDestination;
[\ForwardOnBusyTrunkDest]
For example, the below configuration forwards IP-to-Tel calls to
destination user “112” at host IP address 10.13.4.12, port 5060,
using transport protocol TCP, if Trunk Group ID 2 is unavailable:
ForwardOnBusyTrunkDest 1 = 2,
112@10.13.4.12:5060;transport=tcp;
For more information, see Alternative Routing to IP Destination upon
Busy Trunk on page 520.
74.10.14 Number Manipulation Parameters
The number manipulation parameters are described in the table below.
Table 74-70: Number Manipulation Parameters
Parameter Description
configure voip > gateway
manipulation settings >
map-ip-to-pstn-refer-to
[ManipulateIP2PSTNReferT
o]
Enables the manipulation of the called party (destination) number
according to the SIP Refer-To header received by the device for TDM
(PSTN) blind transfer. The number in the SIP Refer-To header is
manipulated for all types of blind transfers to the PSTN (TBCT, ECT,
RLT, QSIG, FXO, and CAS).

[0] Disable (default)

[1] Enable
During the blind transfer, the device initiates a new call to the PSTN and
the destination number of this call can be manipulated if the parameter
is enabled. When enabled, the manipulation is done as follows:
1
If you configure a value for the xferPrefix parameter, the value
