Hi,

I have successfully integrated Twilio with salesforce, contacts can call the twilio number and get routed accordingly and speak to a company representative, also call and SMS can be made from salesforce.

What I am looking for is when an outside caller calls the twilio number a small popup window should display the contact's details.

How can I achieve this functionality? 

Architecture:

================

Triggering point: Visualforce Page, tied to a Apex Class.

The caller is requested to press "1" to speak to someone, right now the owner of the record is automatically called. (at this point the pop up window should be displayed. which is my requirement)

Page 1 is first invoked which is linked to a controller and the caller is greeted with name and directed to press a 1, when the caller presses 1 it is directed to Page 2 which automatically calls the owner of the contact record.

Page 1:

<apex:page controller="KVTwilioController" showheader="false" contentType="text/xml" 
  >{! '<?xml version=\"1.0\" encoding=\"UTF-8\"?>' }
    <Response>
        <Say>Hello {!name}</Say>
        <Say>Welcome to Neuberger Berman.</Say>

        <Gather  numDigits="1" action="KVTwilioHandleKeyPage" method="POST">
          <Say>To speak to a real person, press 1. Press any other key to start over.</Say>
        </Gather>

    </Response>
</apex:page>

 Controller controlling Page 1:

public class KVTwilioController {
 
  public KVTwilioController() {}
 
  /* return TwiML */
  public String getName() {
    // if the caller is known, then greet them by name
    // otherwise, consider them just another monkey
    String name = 'Hi';
    
    String fromPhone = ApexPages.currentPage().getParameters().get('From');
    if (fromPhone!=null) {
    
        System.debug('~~~~~~~~ KVTwilioController : fromPhone : ' + fromPhone);
    
      // remove the country prefix for Phone field search
      if (fromPhone.startsWith('+1'))
        fromPhone = fromPhone.substring(2);
    
      // search Lead and Contact phone number fields
      List<List<SObject>> results = [FIND :fromPhone IN Phone FIELDS
          RETURNING Contact(FirstName, LastName), Lead(FirstName, LastName)
          LIMIT 1];
    
      // extract the name if there’s a match
      if (!results[0].isEmpty()) {
        Contact r = (Contact)results[0][0];
        name = r.firstName + ' ' + r.lastName;
        
        System.debug('~~~~~~~~ KVTwilioController : Contact Name : ' + name);
        
      } else if (!results[1].isEmpty()) {
        Lead r = (Lead)results[1][0];
        name = r.firstName + ' ' + r.lastName;
        
        System.debug('~~~~~~~~ KVTwilioController : Lead Name : ' + name);
        
      }
    }
    return name;
  }
  
  // if the caller pressed anything but 1 send them back
    public PageReference getHandleUserInput() {
        PageReference p = new PageReference('/apex/KVTwilioHandleKeyPage');
        if (ApexPages.currentPage().getParameters().get('Digits') == '1'){
        }  
        return p;
    }
  
  
}

 Page 2:

<apex:page controller="KVTwilioHandleKeyController" showheader="false" contentType="text/xml"
  >{! '<?xml version=\"1.0\" encoding=\"UTF-8\"?>' }
    <Response>
        <Dial>{!dialNumber}</Dial>
        <Gather action="KVPopUpPage" />
        <Say>The call failed or the remote party hung up. Goodbye.</Say>
    </Response>
</apex:page>

 Controller controlling page 2

public class KVTwilioHandleKeyController
{
  public String getDialNumber() {
    // if the caller is known, then find their owner's phone number
    String dialNumber;
    
    String fromPhone = ApexPages.currentPage().getParameters().get('From');
    if (fromPhone!=null) {
      // remove the country prefix for Phone field search
      if (fromPhone.startsWith('+1'))
        fromPhone = fromPhone.substring(2);
    
      // search Lead and Contact phone number fields
      List<List<SObject>> results = [FIND :fromPhone IN Phone FIELDS
          RETURNING Contact(Owner.Phone), Lead(Owner.Phone)
          LIMIT 1];
    
      // extract the owner phone if there’s a match
      if (!results[0].isEmpty()) {
        Contact r = (Contact)results[0][0];
        if (r.owner!=null && r.owner.phone!=null)
          dialNumber = r.owner.phone;
      } else if (!results[1].isEmpty()) {
        Lead r = (Lead)results[1][0];
        if (r.owner!=null && r.owner.phone!=null)
