[Asterisk-Users] iax2 nativ bridge question?

[Atuc]

hallo all,

i would like to know, as i would suspect, nativ bridiging should work also, 
if only one iax party is behind an nat router and the other has a public 
ip. when i connect to iax clients, which have both pubic ip's nativ 
bridging is working. if one of the clients is behind an nat, the iax2 
channels always get routed through the asterisk server (latest stable 
version from cvs) ?? i have also set the notransfer=no in iax.conf !!

is this normal? in my understanding, it should be possible if one party 
have a public ip to traverse the udp traffic direct p2p.

am i wright?

here is what my asterisk server shows during connection (unable to transfer):

tahnks,
alex
