We've recently got 3CX to work with Twilio and we're sending and receiving without any issues. The next step forward is to 'block' the recipient from being able to send a reply as we're using this to simply send notifications to customers, we don't want them to call or contact us using this number at any time.
Actually, as I write this, I got a text from a company doing just that, the reply field isn't even showing.
Any help would be great.

I am sending SMS using Twilio API. During testing i found that it sometimes delivered message to the phone number but does not sends all the time. This is the case of DND activated numbers(Do Not Call List).
I knew this is because of Sender routing done by Twilio. When Twilio sends SMS using a number(only numeric sender-FROM), i received the message, but when it sends message using some alphanumeric sender(like DM-044138), it does not delivers the message.
Now my question is do we have any access to change this ? Can we set something that could guarantee the delivery even for the DND numbers ?
Any help would be highly appreciated.
Your problem is you are sending it to India.
Please review the following.
This feature is only available when sending messages to supported countries
As you can see from the list below India is not a supported country.

I have built an app that sends out an SMS using the twilio number(the one assigned to me) when a message is sent I receive the SID number which is inserted into the db, along with some other general information, however I do not know how to connect the received SMS SID to the sent SMS SID that tells the system that user has responded....how does someone connect the outgoing message to what is received?
UPDATE:
Hello Devin, Thanks for the response! however, this does not help me much as I might send lets say one of three different people multiple messages in an hour.
my app is a notification app...basically it is a form that a user fills out with some basic info. one of these fileds they choose is a drop down of three different people(who the message will go to) they send the message. my app then inserts the form data explained above along with the SMSID that is returned by you guys into a DB.
the user(one of the three people descibed above) that was sent the notification above responds to the message, meaning that Twilio hits my "Request URL" and I save all the information that is returned by the user...however, and where the problem actually lies is that the SMSID for that reply is not the same as the SMSID of the sent notification...therefore I have no way to connect the SMS that was sent to the user with their response. I have looked at the cookies option and that is not what I am needing...actually your documentation actually acknowledges this issue but does not offer a solution as seen here under "Application Initiated Conversations"

So if you know of a way around this, I would love to hear it for sure :)

The SMS protocol has no concept of a "conversation". Each message sent is unique and has no knowledge of messages sent before or after it. Twilios SMS Sid is simply a unique identifier for an individual message.
The typical way to solve this is to use the To/From phone number pair as the unique identifier of an SMS conversation. When you send your first outbound message, store the To/From phone number in your database. When the user replies Twilio will tell you what number they sent the message to and from and you can use that information to look up the original outbound message in your database.
If a "user" can be involved in several different conversations at once you either need to use a unique phone number for each seperate conversation (allowing you to use the technique above), or you need to have the user include some type of conversation ID in their reply (which you can use as the unique identifier).
You can buy a pool of numbers and as each conversation "ends", recycle the number for a new conversation.
Hope that helps.
My web app sends an SMS text message to users in the US when they enter their phone number, using the Nexmo API. When the SMS contains a link, it does not get delivered to users if their carrier is Verizon or T-Mobile. For other carriers, such as Sprint and AT&T, it does get delivered. It does not generate error messages in any case with Nexmo and I still get charged for the text even if it gets blocked by the carrier.
I contacted Nexmo and they replied:
I would say it is very likely that the link in this sms caused a spam
filter to block this message, especially if other plain content
messages have been delivered to this number successfully. So the issue
with US LVNs is that they are intended for pure P2P traffic and this
is why sending a link might be suspicious and seen as a message
originated from an application. Unfortunately there is nothing we can
do about this as it is set by the US carriers.
These are not definitely not spam or marketing messages. How can I send a link in an SMS message and not get blocked?
I had the same issue recently. All major carriers have some basic checks in place which blocks the SMS from getting delivered if you use short links (e.g.http://abc.gl/1432). The SMS will get delivered as long as you have a .com in the URL (e.g. http://abc.gl.com/1432)
Well, I observed that some carriers mark it as spam if have "Some Message. Click Here http://example/somelink" format.
Removing "Click here" part worked for me.
i.e. "Some Message. http://example/somelink"
Got the same issue. I have been using twilio to a t-mobile phone in the US.
SMS Hello Alan, your code is: 146945 for website.com is not working but
SMS Hello Alan, your code is: 146945 is working fine.
I am new to Twilio API.I have trial account and I have sent Message using Twilio Rest API successfully and received message from number i.e Message as:DM-062107 and body :- Sent from your Twilio trial Account-Hello.
Now I can't able to reply this message.can any one help me to how I can reply to this and how I know that message is received.
I have contacted to Twilio technical support for same problem and get the response. Check the reason why reply option is not enabled:
Although Twilio supports sending outbound messages internationally using toll-free numbers, your Indian number may not support sending inbound messages to US toll-free numbers. I will recommend checking with your mobile carrier to see if sending messages to US toll-free numbers is supported. If not, I will recommend using a regular US number instead of a US toll-free number and kindly retest.

So, to reply to message you just send a normal SMS from your phone to the number. The way Twilio handles this is using a 'webhook'.
If you log into your Twilio account, click on the 'Number' tab, you'll see you have a telephone number there (the same one you sent an SMS with):
Once you've clicked on the number, you'll see a screen with some other details:
Here you can configure your webhook. This is basically a URL that Twilio will send your message to. So if you configure that to point to the URL of some application you have written, you'll receive an HTTP Post or Get request (you can configure which) with the contents of the message, who it is from, etc.
You can then reply to this message with Twiml, which is just XML:
<Response>
<Message>
This is the message that is sent in reply!
</Message>
</Response>
And using this you can build up a conversation!
There are a lot of details on Twilio's website with quick starts etc. There is even a video that talks it through.
Hope this helps.
I would like to send a text message survey (eg. "How happy were you with X service? Reply 1 for satisified, Reply 2 for not satisfied") to multiple recipients. From the responses, I would like to create a report on the recipients that responded 1 vs the ones that responded 2. What is the best way to do this with the Twilio API? Does my app need to store the results from my incoming SMS message or does Twilio store these so I can query the results? If the former is the case and TwiML is involved, how do I parse the response and store the result? Thanks!

Chirag:
So it sounds like you have two requirements here:
Use Twilio to send outbound text messages to different recipients
Capture a users reply to that message
For the first requirement, you can start by going to Twilio.com and signing up for a new account. Its free to start and we give you a Twilio phone number you can use to start to build your app. Once you have the Twilio phone number, you can use the REST API to start sending outbound text messages from that Twilio phone number. We have a quickstart that shows you how to do this:
http://www.twilio.com/docs/quickstart/php/sms/sending-via-rest
Note that this link goes to the PHP sample, but you can use the drop down at the top of the page to pick from other stacks like .NET, Java, Python or Ruby.
Once you've sent an outbound message you need to capture the replies to that message (your second requirement). Twilio uses something called a webhook to notify you about incoming SMS messages.
A webhook is basically a URL exposed by your application and associated with your Twilio phone number. You can configure the URL associated with your phone number in the Twilio dashboard.
Each time we receive an incoming SMS message on your Twilio phone number, we will make an HTTP request to that URL. As part of that HTTP request we send along metadata about the inbound message like the phone number that the message was sent from and the Body of the message. The full list of parameters we send is here:
http://www.twilio.com/docs/api/twiml/sms/twilio_request
Now your app can pull those parameters out of the request and do whatever it wants with them. Since we already are sending the body of the message as we receive it, Tims suggestion of tracking the responses based on the From parameter and storing the message body in your own database is a good suggestion.
This quickstart shows receving an incoming text message, grabbing the From parameter and then responding by sending back from TwiML:
http://www.twilio.com/docs/quickstart/php/sms/replying-to-sms-messages
In your case, if you don't want to reply to the incoming message, just omit the TwiML response.
Hope the helps. Lets me know if you need more info.

Track the responses using the From parameter (and using Body to identify the selection). Yes, Twilio stores those messages, and you could query the API - but it's likely better to just store it in your own database.
