I have no problem doing that by adding the information you have under [general] to /etc/asterisk/sip_nat.conf<br><br><div class="gmail_quote">On Thu, Jan 29, 2009 at 7:30 AM, Holger Latz <span dir="ltr"><<a href="mailto:tech@globalview.de">tech@globalview.de</a>></span> wrote:<br>

Hi all,<br>
<br>
I'd like to connect a softphone at home (nat, dynamic-ip) to a sip-phone<br>
in the office via asterisk 1.4.21 (nat, fixed-ip). SIP works well, the<br>
phone is ringing, but when I pickup the call, there's no audio on both<br>
sides.<br>
<br>
I debugged the rtp-traffic at home. As long as the phone is ringing,<br>
everything is fine. But after the pickup, asterisk sends a SIP/SDP<br>
package with its private address (192.168.100.10). After the softphone<br>
received this package, it tries to send RTP data to this address!<br>
Obviously those packages never reach asterisk...<br>
<br>
Does 'externip' just works for SIP and not for RTP?<br>
Where does the the internal IP-address come from and how can I set the<br>
right one?<br>
<br>
<br>
My configuration:<br>
<br>
[general]<br>
externip = 85.XXX.XXX.XXX<br>
nat = yes<br>
localnet = <a href="http://192.168.100.0/24" target="_blank">192.168.100.0/24</a><br>
