Comment 3 for bug 1276747

Yes the problem is the delay, its not a small delay, takes 20-30 seconds. Let me explain the case here, we have an automated script which makes a dummy call to our phone but there is a limited time till the incoming call keeps ringing and we can only pick the call if we have access to the unity8 object but due to this bug the incoming call dialog is missed.

One workaround would be change the incoming call script to wait for a longer time but I believe that source is not what we (Canonical) develop, so getting changes there can be a pain.

Another thing is that we are not writing a single test, rather I am going to write few more cases as well and we may need to workaround this bug for other test cases as well.
