I am making an app with Twilio API to build a feature to track the call/sms statuses on UI.
For example, if I call to a Twilio number from my phone, on the UI the call status of the number will be dynamically changes.
But currently, as soon as i make an incoming call to the Twilio number, it received the call.
Is there any way that I can make the Twilio phone number take the incoming call programmatically? Just like the way we can hang up the call programmatically.
Thanks!
There is a webhook URL in Twilio account where you can configure your endpoint programmatically

Is there any way to change what events trigger the status callback? Normally you can use statusCallbackEvent but I can't seem to find a way to make this work for the Voice SDK's leg of the call. It works fine on the call leg of the outbound participant, but not the Voice SDK's call leg. I only get completed status event for this leg (and I also can get ringing from the called action url).
Things I tried without success:
Updating the call using the REST api to set statusCallbackEvent to initiated ringing answered completed when the outbound call starts
Setting statusCallbackEvent as an outbound parameter on the Voice SDK's token (in PHP you can set custom parameters using $clientToken->allowClientOutgoing(...) but it seems normal parameters cannot be modified)
I really wish you could set this on the TwiML Application so that any numbers calling out with that application set will just automatically use your set events. That or let me set the parameters on the client's token.
One way to fix this is just to poll for the information but that is an ugly hack and isn't real time.

I don't think you can do what you're asking for here, but for good reason.
When you are placing the call from the Voice SDK, that call leg is then between the application and Twilio. You know the call was "initiated", because you started it. There is no "ringing" because Twilio is not a phone and won't ring. You know it is "answered" because a request is made to your voice URL defined by the TwiML app. And finally, you do get the "completed" event.
As you say, you do get the events for the outbound leg of the call from Twilio to another phone number.
I'm trying to set up a Flow with a Send and wait for reply widget (triggered with the REST API), however, the reply doesn't seem to trigger the next widget (handle_welcome...) and instead triggers the Incoming Message for the Flow (handle_incoming...).
Is there a way to set up a Flow so that it knows that the received SMS is a reply and not just a generic Incoming Message?
Here is a screenshot of the flow:
I only have one number set up and that is set to trigger the Studio Flow on an incoming message.
Also, I'm not sure if it makes a difference but I have Concurrent calls trigger enabled.
Make sure that you do not have the phone number associated to Service. I had created a service, associated the number and that seems to have short circuited the flow. I logged a ticket with Twilio and they kindly instructed me to remove it. Once I removed it, the flow worked as expected:
Remove the number (:warning: if this is not required for your service. Else, purchase a new number and use that with your flow)
Click Remove

To use the REST API trigger with a subsequent wait and reply widget, the phone number you send from can not be associated with a messaging service.
Remove that association and then you will be able to use the flow with both REST API trigger and incoming message trigger.
I have a somewhat peculiar situation for which I can't find documentation: I have an application that will use the Twilio API to initiate a voice call from phone number X (my number) to another one. The problem is that number X could already be in the middle of another call, one that was not initiated with Twilio (so my application wouldn't know about it). Would Twilio detect this, and send an error, or try to initiate the call anyway? If the former, what would the error be? I have found the error code for "callee busy", but nothing similar to "caller busy".
Alternatively, is there an API call I could make before initiating the call to make sure number X is available and not in another call?
Twilio numbers can have multiple calls associated with them, so there would be no error id the Phone X was on an existing call (since phone numbers can be routed however you choose). You can set the outbound CallerID to be another Twilio number or a verified callerID (but if they call that verified callerID back, it wont go back to Twilio but the carrier/business owning that number).
Once the dialed party answers after making the outbound API call, you tell Twilio how to route the other piece (who to connect the answering party to) via the URL parameter hosting the Twilio Markup Language (TwiML).
There is an API call and example for, Read multiple Call resources and filter by call status and phone number (Code Example), you could query before making your outbound call (assuming you always map inbound calls to the same endpoint) or routing your inbound call (which probably makes more sense if you want to re-route to another destination who can answer the call).
The status of this call. Can be: queued, ringing, in-progress, canceled, completed, failed, busy or no-answer.
I'm experimenting with Twilio and I'm confused a bit by the ultimate status of my calls.
Here's what I'm doing. I'm making a call to a Twilio Phone Number which is hooked into an application endpoint. The app makes a database record of the call and then uses Twiml to make a secondary call out to another phone. After the call is complete, the call record is updated with data retrieved from Twilio then a secondary call record is created from the call in my account where its parent_call_sid is my original call's sid.
My issue is, if I call the Twilio Number but let the Twiml Dial timeout, the child call status ends up being 'completed' instead of 'no-answer'.
My question is why is this happening? Do I need to configure how I dial out differently in order to receive the appropriate status for my calls?
UPDATE:
This has been resolved. The issue was voicemail picking up before Twilio's default timeout of 30 seconds ended the call, resulting in a 'completed' status. By reducing the timeout Twilio was able to end the call with 'no-answer' before the voice mail picked up.
The issue was the timeout was long enough for the voice mail to pick up, which does not count as no-answer. Reducing the Timeout so that Twilio ends the call before voice mail answers correctly results in a no-answer status.
I'am using twilio to set up a call between 2 people
I'd like to manage call transfer asked from one side (like when a dtmf key is pressed). The other side could listen to a prompt who could be "please wait while your call is being transfered"
Any chance to do that properly with twilio?
When both parties are connected, Twilio blocks execution of further verbs until the caller or called party hangs up. That's why it is not possible in regular way.
But you can hangupOnStar attribute to hangup the caller party. And set an action URL to continue next dial verbs.
