New problem - Call Failed Not Found

Hi everybody,

some days ago I’ve posted a problem that I was having. Well I’ve solved the problem, but now I’m having another problem, my X-lite when try to call another pc in the same network with X-Lite, returns the error “Call Failed: Not Found”, I think this problem is due to a bad configuration at my dialplan. So I’d like to ask if anyone can post a working simple dialplan, so I can test it.

if anyone could help I would be grateful

Thanks in advance

some additional information

-both of the x-lite clients connects successful to the server
-My Asterisk CLI returns the following error “Call from ‘401’ to extension ‘402’ rejected because extension not found.” (401 and 402 are the number of both clients respectively)
