Random Incoming Call - CID displays "asterisk"
RonR:
I've begun experiencing these calls also. I believe they're a type of VoIP probe or scan from numerous low lifes all over the globe, trying to find a way to make calls at your expense. I've had them from "sipvicious" in addition to "astrerisk". I've not been having much success trying to block them at the InboundCallRoute level. I've got an email into Obihai with a syslog showing the SIP exchanges, but I haven't heard back from them yet. Hopefully, they're analyzing the syslog and will figure out why the blocking is not effective. If I learn anything, I'll post the details.

This sucks!!! Last two nights I got the "asterisk" call at about 5am...I wish there was a way I could block all calls that come in with "asterisk" as the CID.
RonR:
I haven't received a reply or even an acknowledgment from Obihai that they received my syslog and request for help on this issue. The syslog captured the entire SIP exchange from the offender and should allow Obihai to determine why we're not able to block these calls.
Unfortunately, even if we figure out the proper X_InboundCallRoute syntax to block these calls, it will be offset by an existing bug in the OBi firmware that will simply forward these unwanted calls instead of block them if you ever activate Call Forwarding with *72. Obihai has already informed me that they do not intend to fix this problem.

From my limited understanding, changing the default SIP Port from 5060 to say 5064 normally eliminate these types of attempts. Is it permissible to change the SIP port from 5060 to something else on the OBi ATA? Will break anything?

I tried changing the SIP port via the OBi ATA and then my VOIP won't register...I sure hope something gets fixed because receiving random phone calls at all hours of the night sucks.
