SMS FAQ

Can I have the same phone number for Twilio, Aircall and WhatsApp?

Yes, it’s possible. You will need to purchase a phone number on Twilio and redirect its SIP trunk to Aircall. This enables calls via Aircall.

For WhatsApp, you need to add the number as your sender in the Twilio WhatsApp integration.

This way, you can use the same number for calls, SMS, and WhatsApp messages (WhatsApp calls are not supported).

Can I import my mobile phone SMS in Missive?

No. Missive offers no way to integrate with your existing phone number SMS messages. You need to use one of these third party services: Dialpad, Twilio, SignalWire. They are services that allow you to setup a new phone number to which you can receive and send SMS using custom programming or services like Missive. Their main use case are companies that want to offer customer support through SMS as an alternate channel beside email.

Can I send an SMS to multiple recipients at once?

Yes, it is possible with both Twilio and SignalWire SMS accounts. It's important to know that a separate message will be sent to each recipient.

Can I send links in SMS?

Yes, supposing you're using our Twilio SMS integration. You simply need to copy and paste the link to the body of the SMS. The receiving party should be able to click on it.

How can users unsubscribe or stop receiving my SMS messages?

If you are using the Twilio integration, they can simply reply STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, or QUIT to any of your SMS. No new messages will be sent to their phone number.

They will receive the next message: "You have successfully been unsubscribed. You will not receive any more messages from this number. Reply START to resubscribe."

How should I configure Twilio Studio with Missive?

To receive your Twilio SMS in multiple applications (e.g. Missive) you need to use Twilio Studio and create two different webhooks: One webhook to Missive, and one to another software.

Here's how you can configure your first Webhook to Missive:

Create a Flow in Twilio Studio: Go to Twilio Studio and create a new flow. Give it a name that's easily identifiable.

1. Trigger Widget: Your flow begins with a Trigger widget, which is the entry point for incoming messages.

2. HTTP Request Widget for Missive: Add an HTTP Request widget to your flow. Configure this widget with the following settings:

   Request URL: https://callback.missiveapp.com/twilio

   Request Method: Choose POST.

   Content Type: Set to application/json.

   Request Body: Insert the following JSON structure:

   {
     "SmsSid": "{{trigger.message.MessageSid}}",
     "SmsMessageSid": "{{trigger.message.MessageSid}}",
     "ToState": "{{trigger.message.ToState}}",
     "From": "{{trigger.message.From}}",
     "MessageSid": "{{trigger.message.MessageSid}}",
     "AccountSid": "{{trigger.message.AccountSid}}",
     "ToCity": "{{trigger.message.ToCity}}",
     "FromCountry": "{{trigger.message.FromCountry}}",
     "ToZip": "{{trigger.message.ToZip}}",
     "FromCity": "{{trigger.message.FromCity}}",
     "To": "{{trigger.message.To}}",
     "FromZip": "{{trigger.message.FromZip}}",
     "ToCountry": "{{trigger.message.ToCountry}}",
     "Body": "{{trigger.message.Body}}",
     "NumMedia": "{{trigger.message.NumMedia}}",
     "FromState": "{{trigger.message.FromState}}"
   }

3. Connect the Trigger to the HTTP Request Widget: Link the incoming trigger to the Missive HTTP Request widget.

Configuring the Second Webhook for Another Service:

1. Add Another HTTP Request Widget: Add a second HTTP Request widget for the other service.

2. Configure the Second Widget: Input the necessary webhook URL and format for the second service. Ensure the method, content type, and request body are correctly set up as per the second service's specifications.

Link Widgets Appropriately:

1. Sequential Processing: Link the Missive widget to the second service's widget for sequential processing.

2. Parallel Processing: Link the Trigger widget directly to both HTTP Request widgets for simultaneous processing.

3. Save and Publish: After setting up, save the flow and publish it.

4. Assign to a Phone Number: In the Twilio console, assign this Studio Flow to handle incoming messages for your chosen phone number.

This approach should successfully configure two SMS webhooks for one phone number, with one being Missive, in Twilio Studio.

How to block SMS numbers?

There is no out-of-the-box option, but it is possible to create an incoming SMS rule that matches a contact group. The group can be named Blocked numbers, and the rule could trash the conversation. (Screenshot of the rule below)

To block a number, simply add it to the contact group Blocked numbers.

How to import an SMS (SignalWire) account?

Missive needs your Project ID, Space Url and API Token, plus your phone number. All fields are available in your SignalWire dashboard.

How to import an SMS (Twilio) account?

Missive needs your Twilio SID and Auth Token, plus your phone number. Both SID and Auth Token should be available in your Twilio console page. Look for them on the right side of your screen.

Still from the console, you can access your Phone Numbers by the “three dots” button in the sidebar. It should be under the Super Network category. Here’s the link in case you can’t find it. From there, you should have the option to buy a number. Once bought, that is the full number you will need to enter back on Missive. Don’t forget to enter the country code as well (your number should start with a plus + sign).

How to send group texts or SMS?

You can send SMS to Contact groups and/or organizations. When doing this, a separate message will be sent to each recipient.

Contacts can be grouped into both organizations and groups:

• Organizations are typically used to map a group of related contacts (businesses). Each contact in an organization can have a title, department, and location.

• Groups are used to group unrelated contacts.

To quickly send an SMS to everyone in a group or organization, simply search for the group or organization name in the To field of your message draft.

Note that it is not possible to send group SMS (i.e. an SMS to multiple recipients simultaneously in one single conversation). Twilio actually limited access to the group MMS feature as of March 15, 2022.

What does MMS mean?

MMS stands for Multimedia Messaging Service. Unlike text-only SMS, MMS can include graphic elements such as videos, images, audio, etc. Our Twilio integration allows you to send MMS messages.

You must use an MMS-enabled Twilio phone number. This service is currently available in the US and Canada.
