[VoiceOps] Empty Calls

[Richard Jobson]

Hi Mike,

When you have “empty” calls, do you still get some RTP?
Have you tried recording any audio?
Would setting the SBC to clear the call when silence detected, with a variable timer?
Do they come from any particular carrier?
Or NPA-NXX or IP address weighted?

Sounds a nice Big data analysis challenge 😉

Many Thanks & Best Regards,

Are they coming in via your carrier(s), or are they coming from random IPs?

We've been getting "empty" calls for years. BY empty, I mean there's no audio there at all. They're calls from all over the place (I don't think I've traced them all down). We've had them sit on the line for hours (back when our IVR permitted that).

Okay, I'll just deal with it. Now they're hitting our customers too.

To me, it's more annoying than active scam calls because there's doubt if it's real or not. I assume every call not from a current or prospective customer is a scam, so from the content, it's easy to tell.


How are others handling these calls?
