I use the ucm6104 and the ucm6204, is there a way to block calls that start with V?
I am not sure if this number will allways be unwanted
every other day, we get a couple of them, some are telemarketers from foreign countries, most of them are just empty calls, no one on the other end.
I was looking at the Inbound Routes/ Blacklist
Maybe enter V* as Blacklist Number?
will this work, or will it block everything?
also I am curios about calls from Verizon Network, maybe those are also marked with V too?
Location: WA, USA
this is an example of what I see in the CDR:
