Running UCM 6.1. I can add a route pattern without any wildcards and outbound calls are successful to the specific pattern. I have installed the Australian dial plan (AUNP) using 0.@ as a route pattern. Dialing the same number which works as a specific route pattern entry results in a busy tone. I am stripping everything preAt (0) and ISDN debugs seem ok.
Any clues to the solution here would be appreciated.
