Why do I periodically get several repeated calls from "101"?
Stewart:
You could use a random high port, e.g. 47612, though these clowns could be scanning every port on the the entire Internet (conceivably, it would be possible with e.g. a million zombies), so it might not help.
You could also set up InboundCallRoute for the SPx to only accept calls to specific destinations (the DID or account numbers that your providers normally send).
ianobi:
Thanks for the advice. I was never very fond of clowns or zombies :)
Ostracus:
It seems to me a combination will work best. White-listing your providers IPs, changing ports to something nonstandard, and of course RonRs method of sending three-digit numbers to the bit bucket. And yes any filtering on the providers end closed that hole.
ChrisF:
If you change SP1 -> X_UserAgentPort to some random port, I presume you have to do the same for SP1 -> X_KeepAliveServerPort, or does the blank SP1 -> X_KeepAliveServer suggest that this is not a feature that's being used by my setup?
Also, for those of us behind a NAT, I presume we'd have to change port forwarding so that port points to Obi's IP for UDP packets?
lifeisfun:
We got hammered today with these type of calls today on all 3 lines (several in the row on all)
Is this still the best way to stop this? X_InboundCallRoute : {(xxx):},{ph}
Is there way to block incomming calls all together on individual lines?
Thanks
