Problem solved. I found someone else with a similar issue while Googling.
Solution: uninstall SIPp from my Linux package manager (running Fedora 10), and
build from scratch.

Greetings,
I was wondering if someone might be able to assist me in understanding
why I am having problems getting SIPP to register with a proxy, using
authentication. The initial REGISTER request from SIPP receives 401 from the
proxy (as expected); SIPP then re-sends a REGISTER request, but with only
partial authentication credentials. SIPP seems to be omitting some of the
required parameters. There is a telltale empty space and a leading comma that
occur before the nonce parameter in the second REGISTER. I think this is where
the realm, username and password would go. Anyway, the proxy ignores this
second REGISTER request. Wireshark tags it as a "Malformed packet".
Here is my command line invocation of SIPP:
sipp 172.22.20.80 -sf register_clients_sideA_w_auth.xml -inf
clients.csv -l 1 -i 172.22.20.151 -p 5063 -m 1
Here's my SIPP scenario file:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<scenario name="register_clients_sideA_w_auth">
# SideA

Here is the CSV file used as input:
SEQUENTIAL
sipp1;test.azteknetworks.net <http://test.azteknetworks.net/>
;[authentication username=sipp1 password=sipp1];sipp2;test.azteknetworks.net
<http://test.azteknetworks.net/> ;[authentication username=sipp2 password=sipp2]
And here is a trace of the attempted registration. You can see in the
last line of the last packet that Wireshark thinks this is a malformed packet
(and it appears as if Wireshark is right). Why is SIPP not properly filling
out the authentication information?
