I sent the invite(From header is "Anonymous")  from 2002 terminal to Asterisk in this state.As a result, it became the invite authentication error.

[May 19 23:04:27] NOTICE[28383][C-00000003]: chan_sip.c:25473 handle_request_invite: Failed to authenticate device "Anonymous" <sip:anonymous@anonymous.invalid>;tag=31853SIPpTag091
{noformat}
From the log, Asterisk is a signal received from the 2002 terminal, it seems to have recognized that it has received from 2001.

If the From header of Anonymous, I think Asterisk performs a search of the terminal on the basis of the IP address. However, because a search without the port number, I think that the above results.

Can you confirm the problem existence and Workarounds.
I attach a SIPp scenario and asterisk configuration files when performing a reproduction test.

sorry.There was an error in the sipp scenario.
If the correct scenario, asterisk13.9.1 looks to work normally.
Please once as withdrawn.
