not sure if there is any standalone software, but have not heard of 
anything yet (something like sipp but including validation of SIP 
requests/responses according to rfc3261).

But you can build something similar with Opensips:


You would just have to send the calls through opensips, where you 
execute sipmsg_validate()  and log every malformed request.
