> 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.
