Dialling Offline Twilio Client - twilio

I need to make calls to some Twilio clients that will received the call through the browser. The problem is, these clients don't necessarily have their browser open.
I know normally, a user would have to open up the browser and through the twilio util capability and twilio device to turn their browser into a device. And THEN they can receive incoming call.
Is there way to dial clients, when they haven't initialize their twilio client yet?

If you try to dial a client who is not online Twilio will view that as a no-answer. You can get a notification of this by providing a URL for the <Dial> verbs action parameter.
When the call ends Twilio will make a request to this URL with a parameter named DialCallStatus which you can use to determine what happened when Twilio tried to dial the Client.
Hope that helps.

Twilio does not post to my webhook on incoming calls

I have a trial account.
I have set up my webhook url in the number console.
I have set up a node server tunnelled with ngrok.
But when i call my twilio number, twilio does not send response to my
url. Even in the logs, the Request Inspector for all incoming call is
empty.
Since it is a trail account you need to press a key once the call is answered by Twilio to acknowledge it is a trial account before it will execute any TwiML.

Can I return a SIP 302 (Redirect) as a response to an incoming call to my Twilio app?

I would like my Twilio app to be able to redirect the inbound SIP INVITE to a different telephony system in some cases. We are not using Twilio's carrier but using our own (thinQ) for origination and termination via SIP.
I do not want to forward the call via the Dial command as it would keep the Twilio app in the loop during call setup.
Is is possible to do this?

Twilio does not support returning a 302 redirect when receiving SIP as you describe.
When you set up to receive SIP and channel it through Twilio you need to respond to those incoming calls using TwiML and not SIP commands. Like you suggested, you could use a <Dial> which would direct the call elsewhere (including to other SIP addresses if you use <Sip>) but you cannot just respond with SIP instructions or a redirect.
If you do not want these calls to be handled by Twilio, then you will need to adjust your call routing before the SIP is sent to Twilio.

twilio master account make outbound call with subaccount validated number

I need to make outgoing calls from browser and i set capability token with the master account.
Then i make a call request to twilio from browser and return a twiml from my server.
In the twiml, i set the callerId to a subaccount validated outgoing phone number.
When dial to another client, it works fine. But, if dial to a phone number it not work.
From the debugger i saw this error:
it said callerId must be provided for TwilioClient and SIP calls when using Dial.
I dont know why, I need a help.

The phone number in 'Dial' is not shown in output file

I have the following xml
<Dial timeout="10" action="file.php" method="POST">211</Dial>
which dials the hypothetical 211 to try and connect the caller with 211.
When I read what was sent via $_POST, there's no mention of 211.. Why is that?
Not using Twilio client.

I'm guessing you are returning that TwiML, the <Dial> (within a <Response> I hope) when someone calls your Twilio number and Twilio sends a webhook to your application.
I'm not sure where you are looking for the number, 211, in the $_POST object. If it is when Twilio sends the webhook to you then this is before you have told Twilio you want to dial 211 and so Twilio doesn't know anything about it yet. If you are looking for all the parameters that Twilio sends to you in that webhook, check out this article in the docs on Twilio's request to your application in a voice call.
Are there other POST requests that Twilio is making to your application where you are expecting to see this number?

change the voice for twilio number incoming call

We have a twilio number.
When ever any one call on that twilio number then there is an automated voice of twilio play. Can we customize this to a new message?
Thanks,

You can customise Twilio calls as much as you want! I recommend you take a look through this QuickStart for handling incoming phone calls with Twilio which should get you up and running.
To quickly describe it though, you have a Twilio number and that number has a Voice Request URL configured in the number's settings. When you make a call to that Twilio number, Twilio makes an HTTP request to the URL. That URL needs to return TwiML (a set of instructions to Twilio in XML) which tells Twilio what to do with the call.
If you update the URL to something you control and then return different TwiML, then you can change the message and do a whole lot of other stuff with your Twilio number.
