Brief Description

I’m encountering an issue with my call transfer functionality using the TwilioTransferCall and TransferCallVocodeActionConfig in my telephony application, PhraseBasedActionTrigger does not seem to activate as expected, and the call transfer to the specified phone number fails to initiate.

I’m seeking guidance on the following:
• Configuration Validation: Are there any misconfigurations in the provided code snippet that leading to failure?
• Any documents to make this scalable?
• Debugging Strategies: What additional debugging steps can I take to identify the root cause of the trigger and call transfer issues?
• Best Practices?

transfer_action = TransferCallVocodeActionConfig(
    type="action_transfer_calls",
    phone_number="<rep-number>",
    action_trigger=PhraseBasedActionTrigger(
        type="action_trigger_phrase_based",
        config=PhraseBasedActionTriggerConfig(
            phrase_triggers=[
                PhraseTrigger(
                    phrase="I'm transferring you to another agent, thank you",
                    conditions=["phrase_condition_type_contains"]
                )
            ]
        )
    )
)

agent_config = ChatGPTAgentConfig(
    initial_message=BaseMessage(text=f"<my-prompt>"),
    prompt_preamble=agent_task,
    generate_responses=True,
    model_name="gpt-4",
    actions=[transfer_action]
)

telephony_server = TelephonyServer(
    base_url=BASE_URL,
    config_manager=config_manager,
    inbound_call_configs=[
        TwilioInboundCallConfig(
            url="/inbound_call",
            agent_config=agent_config,
            synthesizer_config=eleven_synthesizer_config,
            twilio_config=TwilioConfig(
                account_sid=os.environ["TWILIO_ACCOUNT_SID"],
                auth_token=os.environ["TWILIO_AUTH_TOKEN"],
            ),
        )
    ],
)
