SIP User's Manual 4. ini File Configuration

ini File Parameter Description

AltRouteCauseIP2Tel

This ini file table parameter configures call failure reason values

received from the PSTN 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 Trunk Group

Routing' table.

The format of this parameter is as follows:

[AltRouteCauseIP2Tel]

FORMAT AltRouteCauseIP2Tel_Index =

AltRouteCauseIP2Tel_ReleaseCause;

[\AltRouteCauseIP2Tel]

For example:

[AltRouteCauseIP2Tel]

AltRouteCauseIP2Tel 0 = 3 (No Route to Destination)

AltRouteCauseIP2Tel 1 = 1 (Unallocated Number)

AltRouteCauseIP2Tel 2 = 17 (Busy Here)

[\AltRouteCauseIP2Tel]

Notes:

 This parameter can include up to 5 indices.

 If the device fails to establish a call to the PSTN because it has no

available channels in a specific trunk group (e.g., all trunk group's

channels are occupied, or the trunk group's spans are disconnected

or out of sync), it uses the Internal Release Cause '3' (No Route to

Destination). This cause can be used in the AltRouteCauseIP2Tel

table to define routing to an alternative trunk group.

 For defining the Reasons for Alternative Routing table using the Web

interface, refer to ''Reasons for Alternative Routing'' on page 209.

 For an explanation on usng ini file table parameters, refer to

''Structure of ini File Table Parameters'' on page 293.
