For an unsupported/unrecognized transport, like sctp, 501 might be a
reasonable choice.
It would be a good alternative usage of 501, I agree.
It would be much better than 500 for that case. 500 could
be used if its a *server* problem that you

You have it correct. The proxy's job is to pass the CANCEL on each branch of
the matching transaction. The basic rule of SIP is that all transactions
complete independently. The state of the transactions is dependant only on
the response(s)
The requirement for having received a 1xx response does apply to transaction
stateful proxies. If the proxy does not wait, you have the same issue as you
have with the UA in that the CANCEL could potentially arrive at a downstream
proxy or the UAS before the INVITE.

- Alice calls Bob through a proxy.
- Proxy sends the INVITE to Bob and replies 100 to Alice.
- Proxy gets no provisional response fmo Bob.
- Alice sends CANCEL after a while.
- Proxy replies 200 for CANCEL.
- Proxy doesn't send CANCEL to Bob as

In your case Proxy acts as a UAC for Bob, so Client Behavior applies.
Sorry, I missed your mail. So ok, thanks a lot.

I am looking at implementation of RFC 5626 (SIP-OUTBOUND) and wanted to see
what would be a proper scenario for sending responses for requests received
over a flow which got disconnected before the response was sent. Imagine the
following scenario:
1. Client registers and creates two TCP flows to
10 matches
