asterisk users - Mar 2005 - Asterisk not relaying back the SIP response messages

I see that there is a lot of discussion on the web about a common error 
after installing and modprobe'ing the zaptel driver.  However I don't 
see any resolution, anyone found a solution? 

Here's the output I get after modprobe:

Uhhuh. NMI received. Dazed and confused, but trying to continue
You probably have a hardware problem with your RAM chips

You need a SIP proxy, not a PBX, in order to do that. Asterisk will 
convert all errors from all VoIP protocols into Asterisk error codes and 
then convert them to SIP again. That's simply a result of having two 
multiprotocol PBX's in the call path. You will not see SIP details from 
the dial plan and can't relay it.

We could add a SIPRESULTCODE variable, but I can't see how that helps 
you... It depends on how your two asterisk servers communicate.

No, Asterisk is not a SIP proxy. It is not supposed to "relay" SIP
messages.

If you want SIP relay, use SER, that's what it's for.

HI all,

I have the following setup running:

 EP<--->Calling Asterisk<--->Relaying
Asterisk<--->Softswitch<---> PSTN

The Endpoint EP is registered with the Calling Asterisk. Calls are 
forwarded from this machine to
Relaying Asterisk which in turn forwards it to the Softswitch. In 
addition, this machine also
relays back responses from the Softswitch to the Calling Asterisk.

 Now the problem is that error responses from the Softswitch to the 
Relaying Asterisk are not relayed
 back to the Calling Asterisk. Instead a 403 forbidden error message is 
sent back to the Calling
 Asterisk whatever the error response (503, 484, etc).

  Is there a way to relay back error responses through configuration 
scripts or do I have to dig
  in the source code
