I have a Ruby on Rails application where I was previously using the plivohelper gem for call services. Now, I need to migrate to the vonage gem and make the required changes to ensure the entire call system works seamlessly.

Here's the original code that uses plivohelper

app/interactors/call_activity/connect_backoffice.rb

def dialnode    number  = app_config.voice[@call.state['backoffice_type']].number    timeout = app_config.voice[@call.state['backoffice_type']].timeout    # Here we try to reach the backoffice number within a few seconds. If the call is not answered, the control will be switched to the next activity    dial_node_options = {       dialMusic: sound_callback_path('forwarding_to_backoffice'),       callbackUrl: callback_path('on_bridge'),       callerName: (@call.external_number(true) || '498910003000')    }    if @call.state['backoffice_type'] == 'barred'      dial_node_options[:confirm_sound] = sound_callback_path('barred_user')      dial_node_options[:confirm_key] = '*'    end    dial_node = Plivo::Dial.new(dial_node_options)    dial_node.append(Plivo::Number.new(format_number(number),                                       gateways: Rails.application.credentials.voice.dig(:gateways),                                       extraDialString: "leg_timeout=#{timeout}"))    dial_node    dial_node  endend

app/interactors/call_activity/base.rb

def sound_callback_path(message)"http://#{Rails.application.credentials.general.dig(:internal_url)}/callback/call/sound?url=#{voice_message_url(message)}"end

app/interactors/call_activity/base.rb

def callback_path(action, params = nil)    url = "http://#{Rails.application.credentials.general.dig(:internal_url)}/callback/call/#{action}"    if params.present?      uri = Addressable::URI.new      uri.query_values = params      url += '?'+ uri.query    else      return url    end  end

I have a set of events that I have used using gem aasm to transit one event to another based on action.

app/interactors/call_activity/connect_supporter.rb

def dialplan_connecting    internal = request.supporter.supporter_settings.internal_sip    response = Plivo::Response.new    if app_config.voice.recording      response.addRecord(bothLegs: true, filePath: Rails.application.credentials.dig(:voice.calls_path), fileName: recording_file_name(false), maxLength: 100000)      call_recording_announcement(response)    end    dial_node_options = {        timeout: 15,        callerName: '498910002000',        dialMusic: sound_callback_path('forwarding_to_supporter'),        callbackUrl: callback_path('on_bridge'),        confirmKey: (request.started? || internal) ? nil : '*',        confirmSound: (request.started? || internal) ? nil : sound_callback_path('dial_star_accept')    }.compact    dial_node = Plivo::Dial.new(dial_node_options)    if internal      dial_node.append(Plivo::Number.new(request.supporter.id.to_s, gateways: Rails.application.credentials.voice.dig(:internal_sip_gateway), extraDialString: 'leg_timeout=30'))    else      dial_node.append(Plivo::Number.new(format_number(request.supporter.personal_phone_number), gateways: Rails.application.credentials.voice.dig(:gateways), extraDialString: 'leg_timeout=30'))    end    response.append(dial_node)    response.addRedirect(callback_path('next'))    response  end

I have removed the plivohelper gem and did this

config/initializers/vonage.rb

require 'vonage'# Vonage configurationVonage.config.api_key = ENV['VONAGE_API_KEY']Vonage.config.api_secret = ENV['VONAGE_API_SECRET']Vonage.config.application_id = ENV['APPLICATION_ID']Vonage.config.private_key = ENV['VONAGE_PRIVATE_KEY']# Virtual numberVONAGE_VIRTUAL_NUMBER = ENV['VONAGE_VIRTUAL_NUMBER'].freeze# JWT token# VONAGE_JWT_TOKEN = generate_jwt_token# Vonage clientVONAGE_CLIENT = Vonage::Client.new(  api_key: Vonage.config.api_key,  api_secret: Vonage.config.api_secret,  application_id: Vonage.config.application_id,  private_key: Vonage.config.private_key)

Now, how can I replace the entire work with vonage gem modifying the necessary code and keys so that the features work the same like before?
