I am trying to build a system that captures my media stream when I call into a twilio inbound number. If the user presses the # key, I would like to disconnect the call.
In my nodejs code, I handled the answer call request as:
res.send(`
<Response>
<Say> Welcome to XYZ </Say>
<Gather input="dtmf" finishOnKey="#" timeout="60" action="/completed">
<Stream name="description" url="wss://${req.headers.host}/"/>
</Gather>
</Response>
`);
and my completed method is declared as:
app.get("/completed", (req, res) => res.send(`<Hangup />`));
But the call waits for 60 seconds and media doesn't streams to wss event, though disconnect on pressing # key. Whereas if I write
res.send(`
<Response>
<Say> Welcome to XYZ </Say>
<Start>
<Stream name="description" url="wss://${req.headers.host}/"/>
</Start>
<Pause length="15" />
<Gather input="dtmf" finishOnKey="#" timeout="60" action="/completed">
</Gather>
</Response>
`);
then, the media stream to wss connection but dtmf doesn't works. Any suggestion to solve this scenario?

I'm currently looking at a basic example of create call https://www.twilio.com/docs/voice/api/call#create-a-call-resource.
The TWIML fetched in the url parameter uses the <Gather> verb to call a number via the action attribute then <Say> something on a loop. Once the DTMF input is detected it dials a second number:
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Gather input="dtmf" action="/dial/john" method="POST">
<Say loop="0">Press a key to connect to John</Say>
</Gather>
</Response>
response at /dial/john:
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Dial>415-123-4567</Dial>
<Hangup/>
</Response>
Now, my question is would it be possible to use the API to do the exact same and reduce costs? The cost per minute for each call is GBP0.0175 whereas I believe it could be lower using the API / SIP / VOIP?
TIA
Using you can tell Twilio you want to connect to a PSTN phone <Number>, a <Sip> endpoint, a <Client> ID or even a Twilio Programmable Wireless <Sim> card.
Depending on which if these you use they will have different costs.
Hope that helps.
Is there a way to implement the following in TwiML? The goal is to produce a reasonably-sounding voicemail on Twilio.
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Pause length="15"/>
<Say voice ="woman">
You have reached the voice mail of ##The_Phone_Number_One_has_Called##.
Please leave a message at the beep.
</Say>
<Record
transcribe="true"
/>
</Response>
I have a bunch of Twilio numbers and would like to have the string "##The_Phone_Number_One_has_Called##" replaced by the number that the caller is calling. Please advice if I should deploy a dedicated TwiML for each phone number.
Using Templates with a TwiML Bin, and Polly voices, try something like this for the bin:
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Pause length="15"/>
<Say voice="Polly.Joanna">
You have reached the voice mail of
<say-as interpret-as="telephone">{{To}}</say-as>.
Please leave a message at the beep.
</Say>
<Record
transcribe="true"
/>
</Response>
How to use templates with TwiML Bins

Amazon Polly
(https://www.twilio.com/docs/voice/twiml/say/text-speech#amazon-polly)
You could do it on your server's code. Just replace the "##The_Phone_Number_One_has_Called##" with the phone that the user called.
Remember that you get the number that the user dialed on the post param "To" on each of Twilio's requests to your server, so from your server you could return:
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Pause length="15"/>
<Say voice ="woman">
You have reached the voice mail of $POST["To"].
Please leave a message at the beep.
</Say>
<Record
transcribe="true"
/>
</Response>
And your server will render a different phone each time, and Twilio's will say it. Just a heads up, the $POST["To"] has the format "+1XXXXXXXXXX", so you might want to remove the +1.
Is there a way with twilio to stop the welcoming message (Say) once the caller input digits and then forward it to the next IVR tree without waiting the whole message ?
Thanks
You can use numDigits attribute in GATHER with a integer value.For example, one might set 'numDigits' to '5' and ask the caller to enter a 5 digit zip code. When the caller enters the fifth digit of '94117', Twilio will immediately submit the data to the 'action' URL.
Check detail on Twilio Docs.
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Gather timeout="10" numDigits="5">
<Say>Please enter your pin number and then press star.</Say>
</Gather>
</Response>
Actually I had the Gather after the Say. Instead I should've wraped the Gather around the say:
<Response>
<Say voice="alice" language="it-IT">...</Say>
<Gather method="POST" numDigits="1" action="/twilio/ServletHandleUserInput" finishOnKey="0">
</Gather>
</Response>
So I amended it alike :
<Response>
<Gather method="POST" numDigits="1" action="/twilio/ServletHandleUserInput" finishOnKey="0">
<Say voice="alice" language="it-IT">...</Say>
</Gather></Response>
Thanks Rubai
I want to create the following:
A line number, let's say 741-SUPPORT (just an example), where people can call.
When somebody calls, I want them to listen some text (I use <Say>) and then, forward their call to my number.
When I receive the call, I want to listen to a text that announces me that this call comes from that line, and allows me to press 0 to accept de call, or any other number to reject it.
In case that I accept, both calls get connected. Otherwise, the caller should be able to leave a message.
What I've done so far:
First TWIML used when the caller calls to 741-SUPPORT
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Say voice="alice" language="en-US">
This call is being recorded.
Please hold on, your are being connected.
</Say>
<Dial action="CallEnded.php" timeout="15" timeLimit="600" callerId="+1741SUPPORT" record="record-from-answer">
<Number action="JoinCall.php">+PRIVATE NUMBER HERE</Number>
</Dial>
</Response>
JoinCall.php
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Gather timeout="10" numDigits="1" action="CallAccepted.php">
<Say voice="alice" language="en-US">
You have an incomming call from 741SUPPORT.
Press 0 to accept the call, press any other number to reject the call.
</Say>
</Gather>
</Response>
CallAccepted.php
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<?php if ($_POST['Digits'] == '0') { ?>
<Say voice="alice" language="en-US">
Call accepted.
This call is being recorded.
</Say>
<?php } else { ?>
<Say voice="alice" language="en-US">
Call will be rejected.
</Say>
<Hangup/>
<?php } ?>
</Response>
CallEnded.php
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Say voice="alice" language="en-US">
<?php if ($_POST['DialCallStatus'] != 'completed') { ?>
We had issues connecting the call, please try again later.
<?php } else { ?>
Thanks for your call. Goodbye!
<?php } ?>
</Say>
</Response>
So I would like to know:
How can I play hold music on the caller's side while all the logic is performed?
How can I disconnect from the call and ask the caller to leave a message?
Consider using a Enqueue.
So the person dials in then send them to the queue specifying the waitUrl. (Use this to play music).
When u accept the call dial the queue and pick up the call.
Off the top of my head, if you reject the call then you will have to use the rest api to redirect the call to another url that then says thank you but no thank you.
How would you recommend associating a Twilio call recording with the call?
Is there a parameter that shows which call the recording applies to? Here is the documentation: https://www.twilio.com/docs/api/twiml/record
Or is there a way to pass a custom parameter from my app such as "event_id" when setting up the recording below?
<Dial hangupOnStar="true">
<Conference record="record-from-start" eventCallbackUrl="/twilio/receive_recording_url">custom_conference_id from my app</Conference>
</Dial>
Twilio will pass the recording URL with its request to the "action" url
<?xml version="1.0" encoding="UTF-8"?>

<Say>
Please leave a message at the beep.
Press the star key when finished.
</Say>
<Record
action="http://foo.edu/handleRecording.php"
method="GET"
maxLength="20"
finishOnKey="*"
/>
<Say>I did not receive a recording</Say>
</Response>
http://foo.edu/handleRecording.php will receive via GET:
RecordingUrl: the URL of the recorded audio
RecordingDuration: the duration of the recorded audio (in seconds)
