Bug 1093583 - [DSDS] Add test to make a phone call with default SIM

I'm not sure I understand the question. If you want to test making a phone call with both SIMs, there are a number of ways you could do it. You could have a single test with a for loop, or you could have multiple tests extending a base test case to avoid duplication, or you could write a parameterized test case, such as http://dxr.mozilla.org/mozilla-central/source/testing/marionette/client/marionette/tests/unit/test_data_driven.py
