Answering calls and playing audio is not working

[rodrigomartins806]

Hello, I took the example code as soon as I finished the installation and I am testing it, but it authenticates but does not transmit the audio as shown in the example, I have the following error in the terminal.

Code exemplo

from pyVoIP.VoIP import VoIPPhone, InvalidStateError, CallState
import time
import wave

def call_answer(call):
    try:
        f = wave.open('testeaudio.wav', 'rb')
        frames = f.getnframes()
        data = f.readframes(frames)
        f.close()

        call

        call.answer()
        call.write_audio(data)  # This writes the audio data to the transmit buffer, this must be bytes.

        stop = time.time() + (frames / 8000)  # frames/8000 is the length of the audio in seconds. 8000 is the h>

        while time.time() <= stop and call.state == CallState.ANSWERED:
            time.sleep(0.1)
        call.hangup()
        print('Chegou aqui no call_hangup')
    except InvalidStateError as error:
        print(f'deu erro aqui o  {error}')
        pass
    except:
        print(f'chegou aqui no except do callhangup')
        call.hangup()


if __name__ == "__main__":
    phone = VoIPPhone("10.158.0.3",5060, "201", "PASSWORDSECRET", myIP="10.158.0.20", callCallback=call_answer)
    phone.start()
    input('Press enter to disable the phone')
    phone.stop()

The call arrives, but in addition to the audio not being played, I have the following output on the terminal Error

root@mtic-fusionpbx:/app# python3 call_voip.py
Press enter to disable the phone

  Call is not answered
