Call from Sipvicious

Got a call this morning with the caller ID "sipvicious" and the number 100.
:?

It seems sipvicious is some sort of scanning software searching out SIP devices. When I check my call records in voipfone there is nothing shown.

Presumably as my adapter is connected to the internet it is visible to anyone who wants to search it out.

Is anyone familiar with this software? Anything we can do to avoid it?
If they connect to my adapter directly then presumably the calls don't go through voipfone and so voipfone can't screen them out.

Now that someone has found my device they can presumably start targetting me with junk phone calls.

A google brought up this for me http://sipvicious.org/blog/

I'll have to look at this in depth, not too sure what the risks or implications are. :shock:

Yes - I found that one as well.

It seems like it is a tool set for scanning and testing VOIP systems.

Presumably anyone with malicious intent can just set it scanning IP addresses looking for SIP devices on known ports (eg 5060) and build up a database of known devices.

The resulting database will be a bit like a list of harvested email addresses - ideal for selling to a spammer.

What I'm not sure of is what happens when they find a device. I'm assuming that with the right software they can then just send the appropriate messages to the IPaddress/port and get the phone to ring. Is that possible or does the SIP adapter only respond to commands from the server it is registered to (ie voipfone)?

I live in Canada, using a VOIP, and I recently received a call from Sipvicious 100, when I answered all I got was a busy tone. Prior to this I received calls from 1001 and 1000. The calls from 1000 started out 30 minutes apart for the first 8 hours (annoying as hell) then became less frequent. In a 12 hour period I received a total of 23 calls! If anyone knows how to stop this please let me know...the only other option is to go back to a "regular" telephone provider, but, as we all know the cost is more than double what VOIP charges.

These calls are possible if you're using badly designed phones or software.

The phones we sell on our website only allow calls from our network to arrive at them (or any other providers you may have set up).

Unexpected calls such as those generated as described in this thread are automatically blocked.

If you're suffering from these calls, please let us know the make / model of phone you're using - we'll see if there is a known way to block the calls.

Hi, I am new to this forum but reading this post I thought I was the only victim of this kind of stupid call but after changing my set I think I am okay with this kind of calls, the admins seems very helpful and active on this forum so its nice to read problems and their solutions.

What kind of phone was this? I had this issue with Yealink devices and resolved the issue by setting 'Accept SIP trust server only' in the phones settings.
