receive fax Action

Starts a fax session on an inbound call and receives a tif file to the Aculab media file store.

Received tif files are available immediately to play within an application, but generally take a few seconds to become available elsewhere. See Media File Availability for more details.


The receive fax properties are:

PropertyRequired/OptionalDefaultDescription
progress page optional null A web page request object that defines the web page to be requested for fax progress reports.
next page optional null A web page request object that defines the web page to be requested once the fax session has finished. If null or no page is specified then the subsequent action in the action array will be executed.
encryption cipher optional null The cipher object to be used to encrypt the received fax.

web page request defines how a specific web page is requested:

PropertyRequired/OptionalDefaultDescription
url required - The address of the web page to request.
method optional POST One of "GET" or "POST". The HTTP request method to use when requesting the url.

Progress

The progress page is called after initial negotiation and then after each page that is received. It contains updated information regarding the inbound fax. The progress page will receive instance information containing the property action progress which has details for the fax as follows:

PropertyDescription
action A string. The name of the action for which progress information is being supplied.
progress An object containing the progress information supplied for the current action.

The progress property will have the following properties:

PropertyDescription
negotiated settings An object containing the fax negotiation details, e.g., the modem and data rate. See below.
pages received The number of pages that have been received.

The negotiated settings object will contain the following properties:

PropertyDescription
data rate An integer. The negotiated baud rate in bps, e.g., 9600 or 4800.
modem A string. The modem being used, e.g., V.17 or V.29.
remote subscriber id The remote end ID string.

encryption cipher contains the details of a cipher used to encrypt media files:

PropertyRequired/OptionalDescription
type required The cipher type, currently only "aescbc" (AES algorithm, CBC mode) is supported.

For the aescbc cipher the following properties must be supplied in the cipher object:

PropertyRequired/OptionalDescription
key required The cipher key as a string, either 128, 192 or 256 bits represented as 16, 24 or 32 hexadecimal bytes.
initialisation vector required The initialisation vector as a string, 128 bits represented as 16 hexadecimal bytes.

Returns

The http request to the next page will provide final termination details of the fax session in action result. The filename of the received fax is generated automatically and is sent to the next page. The details are as follows:

PropertyDescription
description A string describing whether the fax was received successfully. The string will be one of 'fax received', 'partial reception', 'not received' or 'not a fax machine'.
seconds duration A floating point value to one decimal place. The number of seconds for which the fax session was active.
pages received An integer. The number of pages that were received.
fax filename A string. The name of the fax tif file in the media file store.

  • Examples:

    • Receive a fax and specify a next page to access the received fax filename:

      "receive_fax":
{
    "next_page":
    {
        "url": "my_fax_handler_page"
    }
}

      The following may be returned to the next page once the fax session has terminated:

      "action_result":
{
    {
        "action": "receive_fax",
        "result":
        {   
            "description": "fax received",
            "seconds_duration": 120.5,

        }
    }
}

    • Receive a fax and save it to an encrypted file, specifying a next page to access the received fax filename. Supply a cipher to encrypt the received fax:

      "receive_fax":
{
    "encryption_cipher": 
    {
        "type" : "aescbc",
        "key" : "1F2DEB2E502A4C8CBA58AB5018BD1506419EEA86DF595D3A431F43FAF57534C9",

    },
    "next_page":
    {
        "url": "my_fax_handler_page"
    }
}

      The following may be returned to the next page once the fax session has terminated:

      "action_result":
{
    {
        "action": "receive_fax",
        "result":
        {   
            "description": "fax received",
            "seconds_duration": 120.5,
            "pages_received": 2,
            "fax_filename": "rest_api/received_faxes/2014/04/22/14_49_10_065ef40a36c312db.44237.tif"
        }
    }
}

    • Receive a fax and specify a next page and a progress page:

      "receive_fax":
{
    "next_page":
    {
        "url": "my_fax_handler_page"
    },
    "progress_page": 
    {
        "url": "my_progress_handler_page"
    }
}

      The following may be returned to the progress page after the first page has been received:

      "action_progress":
{
    "action": "receive_fax",
    "progress": 
    {
        "negotiated_settings": 
        {
            "data_rate": 9600,
            "modem": "V17",
            "remote_subscriber_id": "12345"
        },
        "pages_received": 1
    }
}

      The following may be returned to the next page once the fax session has terminated:

      "action_result":
{
    {
        "action": "receive_fax",
        "result":
        {

$actions->add($r);

      Get the filename of the received fax from the action's next page request:

      $info = InstanceInfo::getInstanceInfo();
$receiveFaxResult = $info->getActionResult();
$receivedFaxFilename = $receiveFaxResult->getFaxFilename();

    • Receive a fax and save it to an encrypted file, specifying a next page to access the received fax filename. Supply a cipher to encrypt the received fax:

      $r = new Aculab\TelephonyRestAPI\ReceiveFax();
$r->setNextPage('my_fax_handler_page');

$cipher = new Aculab\TelephonyRestAPI\AesCbcCipher(
    "1F2DEB2E502A4C8CBA58AB5018BD1506419EEA86DF595D3A431F43FAF57534C9",
    "9B85FAED9AB17570D5A82A31F846443B"
);
$r->setEncryptionCipher($cipher);

$actions->add($r);

      Get the filename of the received fax from the action's next page request:

      $info = InstanceInfo::getInstanceInfo();
$receiveFaxResult = $info->getActionResult();
$receivedFaxFilename = $receiveFaxResult->getFaxFilename();

    • Receive a fax and specify a next page and a progress page:

      $r = new Aculab\TelephonyRestAPI\ReceiveFax();
$r->setProgressPage('my_progress_handler_page');
$r->setNextPage('my_fax_handler_page');
$actions->add($r);

      Get the negotiated data rate from the action's progress page request:

      $info = InstanceInfo::getInstanceInfo();
$receiveFaxProgress = $info->getActionProgress();
$negotiatedFaxSettings = $receiveFaxProgress->getNegotiatedFaxSettings();
$dataRate = $negotiatedFaxSettings->getDataRate();

      Get the filename of the received fax from the action's next page request:

      $info = InstanceInfo::getInstanceInfo();
$receiveFaxResult = $info->getActionResult();
$receivedFaxFilename = $receiveFaxResult->getFaxFilename();
