=Odd incoming calls, not on the CDRs?=
If your phone receives odd calls that are not logged on the AAISP CDR pages, then it may be that calls are being sent direct to your phone from the Internet. This would be because your phone or phone system is not firewalling SIP, and so auto-diallers are trying to make spammy calls to you. The caller id may be anything, but we have seen calls from 100, 150 etc.
Solution: Firewall SIP as explained above.
