Hi all,
Today, I came across an issue while trying to change the phone line via the Jabber SDK.
I've configured two lines on a 7942 deskphone. But I'm only able to use the first / default line.
As written in the document “Cisco Web Communicator SDK JavaScript API” (http://developer.cisco.com/documents/4554576/c849c124-a064-4e01-88e4-b108f8a0cb49)
I used the function switchMode(settings).
Unfortunately I realized that this function is not included in the cwic.js
plugin. Therefore I used the function switchPhoneMode(options). This function
calls the Cisco Web Communicator Plugin with the necessary parameters written
in the documentation.
 
So I passed a new line (which is correctly configured for the Deskphone in CUCM).
The result was an error saying ”eLineMustNotBeConfigured“.
Here is the dump from the softphone log:

So I did another test and passed the line I wanted to change to with the parameter
PreferredLineDN.
This one gave me the error “eTftpFileInvalid”.

May I ask
you to help me with this one?
Thanks in advance.

Hi Simon, we are still looking into your question.  We'll update this thread as soon as we have more information.

Hi Shawn

Thanks for your reply.
I was able to change the line once I explicitly added the mode.
Thanks for your help!

Best regards,
Simon
 
 

The third argument to devicesAvailable is a callback function.  The callback function is defined in the API, but it is up to you to call it in your devicesAvailable function.  The callback function takes three arguments: the phone mode, the device, and the line.  To use a line other than the first line on the phone, you must pass the line you want to use to the callback function.  Here is an example:

$('#registerPhone').click(function() {
    var line = 6002;
    $('#phone').cwic('registerPhone', {
        cucm: $('#cucm').val(),    
        user: $('#userName').val(),
        password: $('#password').val(),
        mode: 'DeskPhone',
        line: line,
        success: function(registration) {
            // Action to perform on successful registration...
        },
        devicesAvailable: function(devices, phoneMode, callback) {
            // Determine which device to use.  We're just going to use
            // the first one in the array.

            // Pass the line into the callback
            callback(phoneMode, devices[0], line);
        }
    });
});
 
This is another area where we need to improve the documentation.
