RE: SIP Stack Error. Please help (Part II)

Inside 

private final boolean hopsBackToMe(String host, int port, String transport);

you have 
 
if ((lp.getIPAddress().equals(host)||lp.getSentBy().equalsIgnoreCase(host))

lp.getIPAddress() != host and lp.getSentBy() returns null, and that throws the null pointer exception

Regards,

Eduardo

Eduardo,

It appears that the topmost route header has a parameter lr=on which
is not a valid way of specifying lose routing. Having said that, i'd
like to investigate this error further. Can you put some println in
the method than bombs and see which of the compares is causing the
null pointer.

Thanks

Ranga.
