Hi Olivier, looking at your command line with -m=1 and at the scenario, I suppose that the repeated REGISTER requests without the authentication header you can see are retransmissions of the initial one, implying that the sipp machine/process does not receive the responses from the Asterisk.
This can have a number of reasons: * wrong population of the headers in the messages generated from the scenario (should not be the case as you've specified -i on the command line) * routing issue (unlikely unless you've intentionally split 192.168.64.0/24 into several subnets or misconfigured the network mask on either machine unintentionally) * Asterisk configuration issue (not permitting incoming registrations from this address/subnet) * firewall issue on either machine So SIPp logs, Asterisk logs, and tcpdump/Wireshark are your best friends. See whether the REGISTER arrives to the Asterisk, what is its contents, and whether the Asterisk responds at all and where it sends the responses.

I'm testing this uac-auth.xml file with the bellow command against an Asterisk instance: sipp -sf uac-auth.xml 192.168.64.250 -au 7005 -ap 7005 -s 7005 -i 192.168.64.45 -m 1 I see that Asterisk challenges incoming REGISTER with a WWW-Authenticate but SIPp does not reply with any new REGISTER with an Authorization header. Instead, it keeps sending first REGISTER. 1. Am I correct to expect, with referenced uac-auth.xml, SIPp to send a REGISTER with an Authorization header ? 2. If negative, what should be changed to in uac-auth.xml to implement this ? If positive, is it correct to expect [authentication] lines in a REGISTER to be replaced with an Authorization built with data coming from matching 401 reply (nonce, realm, ...) ?
