My dial plan includes a number of service codes that include #, largely because I wanted to mirror BT's codes as I know them already. Example, check the divert on an an extension: *#21 (as opposed to BT's *#21#). Everything was working fine. I've just got around to setting up DISA and find that I can't access these extensions as # is interpreted as the end of the dialled string. Is there any way to alter this behaviour, or do I need to go through the dialplan and change anything with a # in?
