X-Lite with Asterisk, help me pls!

I conneted to Asterisk using X-Lite successfully. But when I dial *72 or *73 to hear from Asterisk but I see on X-Lite: “Dial Failed: 404 Not Found”. Is anyone show me how to solve it?

hi,
use *72 as exam:
you should firstly check the [from-internal] in file “extentions.conf”. Make sure that there is a line like this:

include => app-callforward

(because AAH would go to [app-callforward] to match what u have dialed, *72 here)

then go to [app-callforward] in file “extentions.conf”, can you find this context with *72 extention defines there?
