Starting Outbound Services
This describes how to use a web service to start outbound services on Aculab Cloud and how to query for inbound and outbound application status.
An Inbound Service is invoked when a call is made to its telephone number or SIP address.
An Outbound Service is invoked by calling the 'service_start' web service with its Outbound Service Name.
The application status for both inbound and outbound services can be queried using the Application Status web service.
Call prefixes
When specifying telephone numbers and sip addresses Aculab Cloud will treat anything containing only digits, optionally separated by a single '-', as a telephone number and everything else as a SIP address.
One of the following prefixes can be used to declare a specific type of number/address.
Prefix | Description | Example |
---|---|---|
tel | a telephone or cell (mobile) number | tel:441908273800 |
sip | a SIP username@address | sip:contact@example.com |
loc | an inbound service hosted on the same cloud region | loc:my_inbound_service |
webrtc | a WebRTC client identified by the supplied client ID | webrtc:clientId |
con | a conference room name | con:MyConferenceRoom |
When using the tel
prefix for a call destination, the full international number must be supplied.
This must not contain any leading '0'. The leading '+' is optional. The call will be placed with Aculab's default providers.
Aculab Cloud does not support calling premium rate numbers via our outbound provider.

Service Start (REST)
This invokes an outbound service that makes an outbound call and starts an outbound REST application to handle that call.
Authorisation
This API uses basic authentication, using a combination of the cloud id, your cloud account username and the name of the service you are starting and this service's outbound password.
Username : cloudID/username/service_name (e.g. 1-2-0/ bob@ example.com/MyOutboundService) Password : Outbound Service Password Request:
Url : https://ws.aculabcloud.net/ service_start Methods : GET, POST
Parameter Value Description rest_calls string A JSON formatted string containing either a single object specifying where to call or, for Production and Premium accounts only, a list of these objects. An outbound service will be started for each object. outbound_parameters string A legacy alias for rest_calls. unique_id string (optional) If supplied this is a unique identifier for a request. This acts to ensure that duplicate requests to the service_start API are idempotent. A duplicate request will return the list of service references previously started by the original request. A duplicate identifier with different parameters will result in an error.
The JSON objects contain the following parameters:
Property Required/Optional Description to required A string containing the destination for the outbound call. This can be a phone number, SIP address, inbound service address, webRTC client, or conference room name (see Call Prefixes). from required only if to
is a telephone numberA string containing the caller ID (a telephone number or SIP username) for the call. If to
is a telephone number, then this needs to be a validated Caller ID).token optional A string containing a user-defined token of up to 5000 characters that will be passed transparently to the Web App in the token
property of theinstance_info
argument to the page request.outbound_parameters optional A string containing user-defined data that will be passed transparently to the Web App in the this_call.outbound_parameters
property of theinstance_info
argument to the page request.extra_sip_headers optional A list of SIP header objects. These represent additional headers to include in the request to initiate the outbound call.
Returns:
A JSON array of unique service invocation reference IDs.
Example:
https://ws.aculabcloud.net/service_start?rest_calls= [ { "to" : "441908283800", "from" : "441908283801", "token" : "token1", "outbound_parameters" : "some user data" }, { "to" : "sip:bob@acompany.com", "token" : "token2", "extra_sip_headers": [ { "name": "X-AccountInfo", "value": "bob/123456789" } ] } ]
Response:
[ "2e891aea_0.1366641192.77832", "2e891aea_0.1366641192.77833" ]

Service Start (UAS)
This invokes an outbound service that initiates an outbound UAS application instance that makes an outbound call.
Authorisation
This API uses basic authentication, using a combination of the cloud id, your cloud account username and the name of the service you are starting and this service's outbound password.
Username : cloudID/username/service_name (e.g. 1-2-0/ bob@ example.com/MyOutboundService) Password : Outbound Service Password Request:
Url : https://ws.aculabcloud.net/ service_start Methods : GET, POST
Parameter Value Description count integer (optional) by default a single instance is invoked. Specifying more than one (Production and Premium accounts only) invokes multiple instances. outbound_parameters string (optional) the outbound parameter string to be sent to the outbound application(s). Specifying a number of strings, each separated by the delimiter character below, invokes an instance for each one (and count is ignored). Must contain only seven bit ASCII, excluding ^, | and the control characters. delimiter character (optional) the delimiting character when multiple outbound parameter strings are defined(Production and Premium accounts only) unique_id string (optional) If supplied this is a unique identifier for a request. This acts to ensure that duplicate requests to the service_start API are idempotent. A duplicate request will return the list of service references previously started by the original request. A duplicate identifier with different parameters will result in an error.
Returns:
A JSON array of unique service invocation reference IDs.
Example:
https://ws.aculabcloud.net/service_start?
outbound_parameters= destinationForApp1, destinationForApp2& delimiter=, Response:
[ "2e891aea_0.1366641192.77832", "2e891aea_0.1366641192.77833" ]

Service Cancel
This attempts to cancel one or more services that have been queued, but that are not yet running. Once a service is running it cannot be cancelled.
Authorisation
This API uses basic authentication, using your cloud account username and API Access Key.
Username : cloudID/username (e.g. 1-2-0/ bob@ example.com) Password : API Access key Request:
Url : https://ws.aculabcloud.net/ service_cancel Methods : GET, POST
Parameter Value Description service_refs string a list of service invocation reference IDs (as returned by service_start) delimited by the character /. Returns:
A JSON object containing a status for each of the service instances supplied, keyed by their service invocation reference Id. The status for each service invocation will be either: "success", "unknown" or "failed". "success" indicates that the service invocation was successfully cancelled before it was run. "unknown" indicates that the service was not recognised, either because it was incorrect or has expired. "failed" indicates that the service was recognised but could not be cancelled.
Example:
https://ws.aculabcloud.net/
service_cancel? service_refs= 2e891aea_0.1366641192.77832/ 2e891aea_0.1366641192.77834 Response:
