Also delete all spare port and virtual station numbers as these guys are trying to find and opening. Have a look at the SMDR record see if you can see the calls coming in..

Use wireshark to identify the source IP and block it in the router, or better yet, get a list of IPs that the ITSP uses and blacklist all other IPs and only allow the IPs the ITSP use.
