Yep, I just tried it with CCM 4.2(3) and it failed horrifically:
"Directory Number contains one or more invalid characters. Valid characters
for Directory Number are
numbers, the letter X, dashes and the following character(s):
* # [ ^ ] + ? !"
I guess all those IPT gurus on this board who keep saying it works never
tried it either...
I tried it on a CTI Route Point and a CTI port...
