<BLOCKQUOTE type="cite"><PRE wrap="">Adam:
in reference to my first message, the NAT on the SIP/GS (a D-Link router)
has ports 5060 for SIP-registration and RTP ports 5000 to 5008 being
forwarded to the Sip/GS.
The Asterisk server, also behind another NAT (Linksys), has the same ports
opened and forwarded.
is it still impossible?

Nope, it is not currently possible. * behind a NAT for SIP does not work
because the * real IP address is placed in the SDP information,
therefore the 'outside' phone can not send the media stream to *. See my
answers over the last week for the more details and possible work
arounds.
