<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I have submitted bug #2154.</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I believe it is a registration problem. The "received" should never be null in the location table.</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I wanted to cleanup a working configuration so I eliminated the NAT check if the address family was IPV6. This was in the initial request route. I was surprised to see that an IPV6 INVITE would fail. The REGISTERs were good.</p>
