>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 whether or not a problem on this issue.
I attach a SIPp scenario and asterisk configuration files when performing a reproduction test.

■Environment, Steps to Reproduce
{noformat}
◎Asterisk(10.7.120.249)
　・centOS 6.5
　・asterisk-13.9.1
　・Asterisk reads the following configuration.
　　- sip.conf
　　- extensions.conf
◎SIPp client(10.7.120.227)
　①register
　　#cd sipp/register
　　#./uac_register.sh
　　⇒It registers the 2001 and 2002 terminal to Asterisk
　②invite
　　#cd sipp/invite_anonymous
　　#./uac_invite.sh
　　⇒It sends the invite(From header is "Anonymous") from the 2002 terminal to Asterisk.
　　⇒It became the invite authentication error.
