Call object

Get

Those function are used to get the call parameters. The possible parameters are described in the section "Call parameters"

 called_number = caf_call.get :called

List_params

This function is used to retrieve the list of supported call parameters. For example to extract all the possible call params from the the call object and put it in hash.

 caf_call.list_params.each {|param| call[param] = caf_call.get param }

Accept

This function is used to accept a call. It takes 2 arguments, the call parameters (hash) and the route parameters (hash).

Apply route remapping rules

 caf_call.accept out_call, route

Refuse

This function is used to refuse a call with a reason code argument parameters :

 caf_call.refuse :reason => :temporary_failure

The supported values are described in the section "Reason values".

Call parameters

The following call parameters are available in the call object:

  • calling
  • calling_noa
  • calling_npi
  • calling_display_type
  • calling_display
  • calling_presentation
  • calling_screening
  • called
  • called_noa
  • called_npi
  • nap

Notice: All values are documented in the noa_npi_remap.rb script and may change between major release.

Noa values

  • unknown_number
  • international_number
  • national_number
  • subscriber_number
  • network_specific
  • network_routing_national_format
  • network_routing_international_format
  • abbreviated_number
  • subscriber_number_operator_requested
  • national_number_operator_requested
  • international_number_operator_requested
  • no_number_present_operator_requested
  • no_number_present_cut_through_call_to_carrier
  • test_line_test_code
  • non_unique_subscriber_number
  • non_unique_national_number
  • non_unique_international_number
  • call_950_number

Those values will be remapped to the protocol specific NOA value. To provide protocol specific value:

  • call_params[:called_noa] = 0x70

or

  • call_params[:called_noa] = 112

Npi values

  • unknown_number
  • isdn
  • telephony
  • private
  • data
  • telex
  • national

Calling Display Type values

  • unspecified => Type is unspecified.
  • calling_party_name => Type is 0xB1.

Those values will be remapped to the protocol specific Display Information Type value. To provide protocol specific value:

  • call_params[:calling_display_type] = 0xB1

or

  • call_params[:calling_display_type] = 177

Calling Display value

  • call_params[:calling_display] = "Roger Fluffy"

Calling Presentation values

  • unspecified
  • not_available
  • allowed
  • restricted
  • addr_restricted
  • name_restricted

Calling Screening values

  • unspecified
  • no
  • pass
  • fail
  • network_provided

Route parameters

All route may have these parameters:

  • calling
  • called
  • nap
  • remapped_calling
  • remapped_called
  • remapped_nap
  • remapped_profile

Additionally it is possible to add dynamic route attributes in the web portal. These can be referenced by their name.

Reason values

All CMC reason codes are available for use by the routing scripts. See the TBCMC_CALL_REASON_CODE enum in the tbcmc_call.h file.

Notice: These values may change between major release.

   /*!< Nap Status Fields */


If the nap status is part of a substructure, it's name in the routing scripts must be composed of the structure name appended by an underscore and the field name.

For example the name to use for the global ASR percentage is:

 asr_statistics_struct_global_asr_percent


It is also possible to add dynamic nap attributes in the web portal. These can be referenced by their name.

Test parameters

@call_params

That variable should contain a hash of call parameters that will passed to the routing script. This is equivalent to the incoming call parameters.


@nap_list

A list of hash containing the nap statuses. This is equivalent to the nap statuses at the time the call is to be routed.

The nap list is hashed by the nap names in UPPERCASE. It is important to consider this when creating new dynamic route or nap attributes that may nap names that will be used to fetch a status.
