Unfortunately without more information (dialplan involved, complete 
console output, sip show peer 603) it's impossible to fathom any 
potential reason why this is occurring. I suspect that's why nobody has 
responded to you until now. If you can provide that information I'm sure 
we can all help to determine if there really is an issue at work here!
