Forwarding an incoming call to another AAH

I’ve two AAH
AAH1 have 32 Lines on one E1
AAH2 havent any line
Is it possible to transfert few incomming call (selecting by the DID number) to the other AAH ?
For the time beeing the two AAH are conected vias IAX2. Internal call are working, AAH2 can do external call (via AAH1), but I don’t know how to link incoming route to a trunk!

search for ‘dual servers’ in the Wiki of my signature. you will probably need to bypass the web interface and configure this directly in the config files.
