CUCM Background Deployment (Custom Image Upload for IP Phones )

After Upgrade CUCM 10.5 to 11.5 we are unable to push images in IP Phones.

1 Check Image resolution and size

2 Upload all images as .PNG and XML

3 Restart TFTP service

Now I can manually select image as background image, Now i have a Question we are unable to push images through third party application (Previously i Used VOIP INTEGRATION-Background Deployment) Also checked AXL services and User settings but unable to push images. I have to push images to 100 ip phones at ones

I really appreciate If anyone suggest me to a method or application to resolve this
