<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>I have an Asterisk server, running 1.6.0, on my home network. It has an IP address of 192.168.0.201. The server is behind my Linksys router that does NAT for my home devices. I have a softphone on my Mac that is on the same NATed network as the Asterisk server. It has an IP address of 192.168.0.1. I have tried this with a Grandstream phone with the same results.<BR>
<BR>
The Asterisk server registers with a SIP provider and seems to maintain a registration.<BR>
<BR>
When I try to dial out from the soft phone or the Grandstream via the SIP provider I get a "Bad Request" response from the provider. I am guessing that many of the packets have my internal address and need my public address.<BR>
<BR>
Is there some way to resolve this?<BR>
<BR>
Here is the relevant entry in extensions.conf:<BR>
<BR>
exten => _88X.,1,Dial(SIP/${EXTEN:2}@proxy01.sipphone.com,20,r)<BR>
exten => _88X.,n,Hangup()<BR>
<BR>
<BR>
Here are my entries in sip.conf:<BR>

Looking at the SIP debug transaction I do not see my public IP address at all. There must be some setting about the server having at NATed address.<BR>
