Before / after — record a voicemail in XML

<?xml version="1.0" encoding="UTF-8"?>
<Response>
  <Say>Please leave a message after the beep. Press pound when finished.</Say>
  <Record action="https://yourapp.com/voicemail"
          method="POST"
          maxLength="120"
          timeout="10"
          finishOnKey="#"
          playBeep="true"
          transcribe="true"
          transcribeCallback="https://yourapp.com/transcription"/>
  <Say>Thank you. Goodbye.</Say>
  <Hangup/>
</Response>

from twilio.twiml.voice_response import VoiceResponse

resp = VoiceResponse()
resp.say('Please leave a message after the beep.')
resp.record(
    action='https://yourapp.com/voicemail',
    method='POST',

    finish_on_key='#',

Before / after — start & stop recording on a live call

from twilio.rest import Client

client = Client(ACCOUNT_SID, AUTH_TOKEN)

# Start recording on an in-progress call
recording = client.calls(CALL_SID).recordings.create(
    recording_channels='dual',
    recording_track='both',
    recording_status_callback='https://yourapp.com/recording-status',
)

# Stop it later
client.calls(CALL_SID).recordings(recording.sid).update(status='stopped')

​

Before / after — list, fetch, and delete recordings

# List recent recordings
for rec in client.recordings.list(limit=20):
    print(rec.sid, rec.duration, rec.media_url)

# Fetch one
rec = client.recordings('RE0123456789abcdef0123456789abcdef').fetch()

# Delete one
client.recordings('RE0123456789abcdef0123456789abcdef').delete()

Transcription callbacks

from flask import Flask, request

app = Flask(__name__)

@app.post('/transcription')
def transcription():
    text = request.form['transcription']
    recording_id = request.form['recording_id']
    # ... persist / index / route the transcript ...
    return ('', 204)

Key differences

• Stopping a recording is a single call. Vobiz’s record_calls.stop_recording(auth_id, call_uuid) stops the active recording by call — you address the call, not a separate recording SID, so there’s less state to carry through your app.
• One <Record> for whole-call capture. Where Twilio recording is split across TwiML attributes and REST resources, Vobiz’s <Record recordSession="true"> captures the entire session (including later Speak/Play and bridged legs), and startOnDialAnswer="true" begins capture the moment the far leg answers.
• Transcription is a two-tier auto / hybrid choice. transcriptionType="auto" uses the default Vobiz engine; hybrid blends Vobiz for common languages with a third-party provider for the long tail — a single attribute covers broad language coverage.
• A dedicated callback for file readiness. Vobiz’s callbackUrl fires when the recording file is actually downloadable, so your download/processing job starts on a real signal instead of polling after the action URL returns.
• Explicit auth_id everywhere. Every recording method takes the account auth_id as its first argument, which makes multi-account and sub-account workloads explicit and easy to route.
• Auth headers instead of Basic auth. Vobiz authenticates with X-Auth-ID + X-Auth-Token headers against https://api.vobiz.ai/api/v1; the SDK sets these for you from api_key / auth_token.
• Familiar verb and attribute names. action, method, maxLength, timeout, playBeep, and finishOnKey keep their Twilio meanings on the Vobiz <Record> verb, so most of your recording XML ports with only the callback/transcription attributes renamed.
