Auto incoming calls to 3CX Windows Client from "15710000000"

[amitjogi]

I have on-premise setup of 3CX PhoneSystem. I am receiving automatic incoming calls to my 3CX Windows Client with caller ID 15710000000. It takes up all the 5 lines one after other. Moreover, I am not able even receive or drop these calls.

Need some urgent help on this malicious behaviour.

Thanks

Hi Amit,

Are you only using soft-clients or desk phones also ? how often does this happen and is it often enough that you can run a PCAP trace from 3CX.

It could possibly be SIP Viscous:
