Hello,

if the message processing gets to config file, there is a condition on sanity check (see sanity module) -- if that condition fails, a reply is sent. But if the processing does not get to config file, means that mandatory SIP message structure was not met - no reply can be built based on sip requirements.

Cheers,
Daniel

in the log the error is "ERROR: <core> [receive.c:165]: ERROR: receive_msg: no via found in request"

I do get the parse error.
Still, I think that even if kamailio stoped processing the request, an error reply should be sent back the the request sender, no?
Something like - 501 ??
