[Asterisk-Users] NTT (Japan) Voip Adapter

[Jason Frisch]

Hello all..

In an effort to find a reasonably priced analog VOIP-TA here in Japan, I 
came accross one
made by NTT for just over $100 (most are over $400). I have been able to 
call out fine, but incoming
always gives me a  "404 Not Found".

I don't think the different IPs are related (this is just because 
Asterisk is in the middle)
Is there anyway to get the same Via and Record-Route headers?
