Calling Party

N2FE Flow Operation - Calling Party

The CallingParty selects an exit according to best-matching of the Calling Party’s logical address against a list of prefixes defined in the operation instance. This operation is similar to the CallerLocation operation, but with two key differences:

The “logical address” is the caller’s “directory number” or public phone number associated with the caller. In many cases, the caller’s “logical address” is the same as their “network address” (physical handset routing number), although in some networks with number porting logic present, these addresses may differ.

The CallingParty operation must have at least one exit. The CallingParty operation is only useful when it has more than one exit, although this is not enforced by the operation definition.

Config Parameters

The CallingParty operation config attributes are as follows.

Parameter Type Description
rules Array of
Object
[Required] The rules Array must contain none or more Objects.

Config Rules

A CallingParty operation rules Object is as follows.

Parameter Type Description
prefix String The prefix which must match in order to branch down the associated exit.
exit_idx Integer The zero-based index number down which to route calls from callers with address matching this prefix.

Note that if one or more prefixes match, then the longest (best match) prefix will be used.

If no prefix matches, then the first exit (index zero) will be followed for Default processing.

Example Operation

Here is an example CallingParty operation in JSON representation.

    {
        "id": 5,
        "type": "CallingParty",
        "base_node": 1,
        "config": {
            "rules": [
                { "prefix": "021", "exit_idx": 1 },
                { "prefix": "022", "exit_idx": 1 },
                { "prefix": "027", "exit_idx": 1 }
            ]
        },
        "exits": [ 4, 17 ]
    }

In this example, calls from a calling party with a prefix of 021, 022 or 027 will proceed down exit 1 to operation ID 17, while all other calls will down exit index 0 to operation ID 4.

Exits

The first exit is always the “Default” exit.

Exit Index Name Description
0 Exit #1 (Default) [Required] All CallingParty operations must have at least one exit.
1 Exit #2 + Additional exits may be present.
