Hello,
there are some mandatory SIP headers, without them a sip reply cannot be
built.
One is Via as the SIP mandates to send the reply where the last Via
address points to. In RFC3261, Via also carries the branch parameter
that should be used to match the transaction.
Cheers,
Daniel

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 ??

I think in such cases you get a "parse
error" in the log. Do you?
If yes, then Kamailio stops processing the packet and no reply is sent.
