[General] 900 Premium Service calls over SIP and/or XMPP?Can 900 Premium Service calls be made over SIP and/or XMPP? I'm not interested in making such calls, just want to avoid any such billing.

Depends on the VoIP provider, there is no technical reason they cant. |

said by OzarkEdge:Can 900 Premium Service calls be made over SIP and/or XMPP? In theory, yes.. But, US 1-900 are pretty much a thing of the past, ever since the last remaining provider of 1-900 numbers in the US, MCI, stopped offering them. [1] AFAIK 1-900 numbers are still alive and well in Canada [2], but IDK of any SIP provider that allows one to connect to a 1-900 number. There are also "international premium rate" numbers.. Ie, where it is an expensive international call, and the callee gets a revenue-share of the interconnection costs. Sometimes these numbers are within NANPA, but still international from the US and Canada.

I thought the availability of premium rate services was based primarily on the class of service the DID was assigned? |

While you might be able to complete a call to a pay-per-call premium number (900, 976, etc), billing for the call would require specific billing and collection agreements between the provider of the service you are calling (be it the weather forecast or porn) and your provider (and sometimes providers in between). I don't know of any VoIP provider that has entered into any such billing and collection agreements, so even if the call completes you would not likely be billed for it. So it is highly unlikely you would be charged for such calls, but best to check with your provider if you are concerned.
Pay-per-call billing was easy when there was only one carrier providing local phone service in a given community. With the advent of competing providers besides the LEC - CLECs, cable-TV, Voip, mobile services, etc, effective billing and collection became damn near impossible. That's one of the reasons the pay-per-call business fell apart (the big reason of course being the advent of the Internet). |

Must have made for good times when they got home. I remember the computer viruses that would attempt to make 900 calls as well. Another service that is quickly dieing is the collect call. Increasingly fewer consumers have the ability to receive a collect call. |

[My virgin experimental Asterisk server of a few days old is already getting hammered, or should I say devirginizingly drilled hehehe... Next step is Fail2ban, I presume...]

This has nothing to do with viruses. Your Asterisk box is exposed to the internet with port 5060 open. There are thousands of SIP scanners out there trying to break into IP PBXes either by guessing extension passwords, or by attempting to place calls like the ones you're experiencing. If you don't have peers registering from outside your network, you should close port 5060. If you need to have the port open for external registrations, consider one or all of the following: - changing the SIP port 5060 to a non-standard port - implement selective firewall rules based on the source IP/country/area - implement fail2ban (and optionally patch chan_sip to catch all the break in attempts). |

I know these are generally not viruses (though some could be infected zombie PCs). But it's malware and certain types of this malware is apparently designed to call revenue-sharing high cost destinations...which smells a lot like the good ol' analog modem dialing ATDT1-900-HOTT-XXX; Anyway, thanks for the valuable security advice. I'll implement these measures as soon as I learn how to actually use my new deflowered Asterisk server.  |

said by 79176722:I know these are generally not viruses (though some could be infected zombie PCs). That's absolutely correct, some of these could actually be installed as malware on infected PCs that work "collectively" at cracking passwords and when they find something they send it back to the "mothership". I guess what I was trying to say is that's it's very unlikely that those attacks on your Asterisk are actually generated by malware that runs the same Asterisk server. |
