The SipXcallController is a RESTful service for third party call control. It is bundled as a jar file and is loaded by the sipXrest container on initialization. It is invoked by HTTP Post to a specific URL.
The SipXcallController implements a third party call controller. The third party call controller works by either sending an INVITE to the calling party and subsequently sending that calling party a REFER to transfer the call to the called party (fire and forget) or by staying in the call path using the call flow 4 of RFC 3725.
The latter method allows subsequent control of the call such as being able to transfer the call after call setup.
The call controller tracks the state of the call in progress for a specified period of time after the call is placed and provides this status for query by applications.
The security model for these operations is enforced by the sipXrest container. That is, when the operation is invoked from the trusted domain using HTTPS, no pin is required. Otherwise, a pin must be supplied for the operation to succeed.
The service is initiated using HTTPS using HTTPS post and queried using HTTPS get. HTTP is also supported with Digest authentication but it is not the preferred method of service invocation.
If you are issuing the curl command from a trusted host ( i.e. one where sipx proxy is running) please use only HTTPS (no authentication is required).
From a non-trusted host you must authenticate the curl command with Digest authentication.
There are some examples with notes in the source directory. Download the source code from svn and take a look at the scripts in sipXcallController/test
6666 is the HTTPS port.
6667 is the HTTP port.
You can use either HTTPS or HTTP when issuing the curl command from a non-trusted host.
Since version 4.6 you should use the redirector in sipxconfig as using port 6666 seems deprecated. The REST interface can be reached (using digest authentication) on http(s)://<host>/sipxconfig/rest/my/redirect/callcontroller etc.
The URI is as documented below:
URL Pararameters (Optional)
sipMethod=[REFER|INVITE] the default is REFER
Initiates a call from the callingUser to the calledUser
All URL parameters are ignored. Note that you an only get the current call state of you have previously initiated the call from callingUser to calledUser
Get the current call state for any ongoing call between callingUser and calledUser
Using curl, you would initiate a call from callingUser to calledUser from a remote host as follows:
Or as an agent (third party)
The following example is to initiate a call between user1 and user2 as user1 who is the calling party.
An example to initiate a call between user1 and user2 as user3 who is a third party agent.
On success, HTTP 200 OK returned. no message body.
On Failure, corresponding HTTP status code returned and more plain/text details contained in the message body, for example. "not valid user pin".
Similar to "place a call", the query can be made either from calling party. The URL is exactly the same as that you would use when placing the call but the method is GET.
Here is an example of how to query call setup progress for call between user1 and user2 as user1.
Here is an example of how to query call setup progress for call between user1 and user2 via agent user3 from sipX trusted domain, no password required.
Here is an example of how to query call setup progress for call between user1 and user2 via agent user3 from sipX's non-trusted domain.
Return result from the query above
If the transfer is invoked using REFER, the calling party records the NOTIFY bodies and reports it (uninterpreted) when the user issues an HTTP GET to fetch the call status. This is reported to the caller when a GET is performed as shown below:
