Mohammed, AT&T is working with the vendor on a fix.  It has to be compatible with all other protocols and services running in this network. This is not a small network and so these things take a bit of time. It will be done, but perhaps not fast enough for you. There's certainly no telling whether the other carrier you reference is using the exact same platform as AT&T, or services. We're cautious about these things.
