> It's a real pain to find the INVITE in SIP DEBUG that generated the retransmission. The timeout for the retransmission generates a NOTICE, but not the INVITE itself. 
> I suggest a NOTICE for any INVITE with "No matching peer", just like the "Wrong password" NOTICE. This would allow fail2ban, among others, to block the address.
