According to this article it is possible to recover the complete AES
encryption key by monitoring traffic (ie sniffing).  I have not yet had
time to review this method to see if it requires a bunch of special
situations to occur or not.  They state that its based on the AES
algorithm and not the specific algorithm which indicates that anything
that does AES can potentially be compromised (including some
cryptophones, and other applications).  Anyone using AES to secure their
VoIP traffic (VPN for example) may want to look for alternatives.
