Hi guys, we are getting spam calls from outside with caller id from our pool. So phone numbers were spoofed ... What steps can be done to prevent /block this callers?

its coming via ITSP sip trunk via cube. SOmetimes it shows desk phone number called to the same desk phone number, some calls shows on sip user A cell phone dialed to user A desk phone . we can't block their cell phone numbers obviously :) but should be some way to prevent this , right ?

ok, looks like we found a way, so on the cube we has programmed his did in blocked list , so user will not get any calls again from his own did. we will probably need to created more of this blocking rules ...
