I'm trying to find the fastest way to get a Conference Sid from an ended call's request. Since the Participant is removed from the Conference when the call ends, searching isn't possible (and not implemented in the PHP library anyways). I'm assuming the call left the most recent Conference, since its 'action' parameter is associated with its Dial into the Conference.
How do I get the most recent Conference using the PHP helper library?

I don't think there is a way to just get the last conference directly from the API. What you can do is use the helper library to get a list of the conferences.
$client = new Services_Twilio('AC123', '123');
foreach ($client->account->conferences as $conference) {
print $conference->date_created;
}
When you do, each conference should include a DateCreated and a DateUpdated property that you can sort by to find the last one created or updated.
Hope that helps.

I'm trying to add a participant to an existing conference. It works just fine, but now I want to add a statusCallback to be called when the ringing begins for the new participant.
Here's the line where I'm creating the new participant:
client.conferences(conferenceName).participants.create({
from: `client:${fromAgentId}`,
to: `client:${toAgentId}`,
statusCallback: statusCallbackUrl,
statusCallbackEvent: "initiated ringing answered completed",
statusCallbackMethod: "POST",
});
As I said, the new participant is successfully getting added to the conference, but the statusCallbackUrl never gets called.
According to these docs https://www.twilio.com/docs/voice/api/conference-participant?code-language=Node.js#parameters-1 it looks like the participants.create() method should accept a statusCallback, so I have no idea why it's not working. If anyone has an idea, I'd love to hear from you.
Answering my own question here.
It seems like it's a problem with the Twilio docs. Regarding the statusCallbackEvent parameter, the docs state:
Can be: initiated, ringing, answered, and completed. Separate multiple values with a space.
However, rather than separating multiple values with a space, the statusCallbackEvent parameter should be an array of values.
I want to join Webex conference using Twilio api. I am using Call class like this:
Call call = Call.creator(toNum, fromNum, twiMLUrl).setSendDigits(dialCode).setStatusCallback(STATUS_CALLBACK_URL).setStatusCallbackEvent(callbackEvents).create();
Here fromNum is my Twilio number, toNum is the phone number provided by Webex and dialCode is the participant code
I am unable to join the conference. I feel it is because webex asks to enter "1" to confirm the participant code in the end while joining.
Is there a way in api to send that "1" to confirm?

It's a little bit blunt, but you can send pauses as part of the sendDigits parameter. Every "w" you send as part of the string will pause for half a second.
It might take a bit of testing, but you should be able to make your dialCode out of the initial code, say "1234", a few pauses and then the final "1". Like 1234wwwwww1.
Let me know if that helps at all.
I am looking into the possibility to implement call tracking with Twilio.
What I would need is that right at the start of an incoming call I would like to be able to change the destination number for that call.
How is this achievable with Twilio via API?
Reading the API docs I found the that there is a real-time call and message routing feature (here) and followed the example (here) but it's not what I would like to achieve.
Thanks ahead for any suggestion and help!

You absolutely can dynamically change the destination number for calls on Twilio. When you are forwarding calls you use the <Dial> noun in TwiML like so:
<Response>
<Dial>YOUR_NUMBER_HERE</Dial>
</Response>
However, if you serve your TwiML dynamically you can return whatever number in the <Dial> tag that you want, based on whatever conditions you want. For example in Ruby using Sinatra:
post "/voice" do
if params["From"] === SOME_SPECIAL_NUMBER
number = FORWARDING_NUMBER_1
else
number = FORWARDING_NUMBER_2
end
"<Response>
<Dial>#{number}</Dial>
</Response>"
end

I'm using Java but the question is language-agnostic, so I posted it under twilio-PHP tag too.
My application needs to connect two customers: A and B. I want to transcribe the conversation and find out whether one of the parties did not pick up and screened the other to voicemail.
I'm following the steps in the click-to-call-tutorial
However, it looks like the Rest API supports recording but not transcription. I successfully can do:
Map<String, String> params = new HashMap<String, String>();
params.put("From", myTwilioNumber);
params.put("To", customerAPhoneNumber);
params.put("Url", "http://MyHandler.jsp");
params.put("IfMachine", "Hangup");
params.put("Record", "true");
Call call = client.getAccount().getCallFactory().create(params);
which gets the entire conversation recorded, but not transcribed!
As a side note -
params.put("IfMachine", "Hangup");
indeed hangs up, when reaches voicemail, but not before leaving a voicemail with random noise. Looks like Twilio's "probing" the response, and by the time it understands it got to voicemail, background noises have been recorded. Which is terrible user experience. Any advice?
Additionally, my call handling servlet does:
TwiMLResponse twimlResponse = new TwiMLResponse();
Say sayMessage = new Say(
"Hi, customer A, stay on line to speak with customer B?");
twimlResponse.append(sayMessage);
Dial dial = new Dial(customerBPhoneNumber);
twimlResponse.append(dial);
But when I'm looking at the TwiML Verbs , there is no place where I can set params.put("IfMachine", "Continue") . So the field call.getAnsweredBy() is null for the second call. In other words, I cannot know whether conversation between customer A and B ever happened.
Additionally, [TwiML Verb Record] ( https://www.twilio.com/docs/api/twiml/record ) does allow transcription, but if I do
twimlResponse.append(new Record());
it stops the conversation and records one of the customers.
So I cannot direct the REST API to transcribe, and TwiML Verbs does not even record the conversation in a way I want.
Can anyone help?
Thanks.

I'm afraid that when recording both legs of a call, using the REST API, then transcription is not available. Transcription is only available on single messages recorded by the <Record> verb when the recording is under 2 minutes long.
I'd recommend recording the call and downloading the file to be sent off to a third party transcription service in order to transcribe longer, 2 legged calls like that.
In terms of the answering machine detection, it is an experimental feature and requires Twilio to listen to the first few seconds of a call to work out whether it is a machine or not. A good alternative, which can work as part of your <Dial> verb as well, is to use call screening. This is a good article on the pros and cons of AMD, as well as a good description of using human detection by call screening.

I am working on making conference calls from twilio client using REST apis.
I am using java helper libraries to call each participants and as they accept they are put to the same conference room. I am successful up to this. The code which returns the xml for conference, I have put in python following the code of server.py present in android sdk.
Currently in server.py I have hard coded the conference name, i.e anyone who tries for a conference will end up in same conference room.
So I want to make it dynamic. I want to pass the conference name from my java code to the url where server.py and the conference xml is present.
I have tried the following.
I tried adding one extra parameter to the call parameters as
callParams.put("To", user); // Replace with a valid phone number
callParams.put("ConfName", "kevin");
callParams.put("From", my_twilio_num); // Replace with a valid phone number in your account
callParams.put("Url", "https://dyno-name-conference.herokuapp.com/conference");
final Call call = callFactory.create(callParams);
where ConfName is my intended conference name. and I tried to retrieve it in server.py like
ConfName = request.values.get('ConfName')
response.dial(callerId=caller_id).conference(ConfName)
But the ConfName is not getting retrieved.
Is there a better approach for this.
I thought of passing an extra parameter along with the url as I see from the answer here. But I am not successful in that too.
May I know if there any correction in above approaches or a different approach for this..
Thanks in advance.
I managed to get it work.
I used the url as
call__Params.put("Url", "https://dyno-name-conference.herokuapp.com/conference?conf_name=kevin");
and in server.py I accessed it as
conf_name = request.values.get('conf_name')
