We are seeing a relatively high number of strange calls hitting a portion of our Toll-Free numbers. The ANIs are mostly disconnected/invalid. When our system answers, we hear silence, a DTMF tone, and then a fast busy on the inbound RTP stream.
We are seeing this over multiple TF vendors. Is anyone else seeing anything like this out in the wild?
