Hi Jeff,
Thanks for that, I'd say that'll probably do it, but I forgot to mention that we have to prepend 61 to 1800 numbers as well. I don't dial them that often so I just dial the trunk preselect before dialing and that has been working. I'm having some trouble with G729 licensing so I can't really test this just yet. I'll let you know how it goes when I get the G729 sorted out.
Many Thanks,
Lloyd
