Hi all I have a network with nodes with different network-interfaces (e.g. node17 with interfaces A and B and node18). Asterisk listens to 17.A, 18's DUNDi knows 17 by knowing ip B. When I start a DUNDi request from 18 to 17 I get a response from A via B. So B knows that the number can be reached at 17.A which is correct. A ----------- B ---------- --------------+ 17 +-----------------+ 18 | ----------- ---------- But when I call this number and debug the IAX-transmissions I get something like: NEW from 18 to 17.A AUTHREQ from 17.B to 18 (f....) INVAL from 18 Why comes this AUTHREQ from 17.B and not from 17.A? Why can't I directly speak with the main IP over IAX? The whole thing works great when DUNDI is connected directily to the IP ASTERISK listens to. What can I do? Thanks for your answer. Best regards Andr?
