Re: [OpenSIPStack] Received response without transaction issue

Indeed.  The log indicates that the first call succeeded.  This only 
strengthens the argument that this most likely is a network issue rather 
than an OpenSBC one.   As I said, ethereal would have helped narrow the 
problem down.

Are you trying to bypass an ISP filter here?  If so, we have also 
experienced blockage of messages coming from port 5060.  I can see that 
your OpenSBC is configured to use the default SIP port.  Is it possible 
that you filter is simply dropping messages coming from port 5060 at random?
