For some reason, it does not reconise 0 being the same as +61.
So for the same phone number, i would have two threads, one with 04xx xxx xxx and another one with +614 xxxx xxxx. It really annoys me and would like to know if there is a fix for this so that the two will be in one thread.
I'm not sure it this is what you need but try going to phone options and scroll to smart dialing. Set your country code and change Use "--" for National Dialing to No.
