Pretty much. We've received calls here with the CID displaying as our own info, and others coming up as a neighbor's number. Some even appear as law enforcement when they're scammers looking for donations to charities that don't exist. I suppose if you're going to commit one crime, go for broke. > This is what I have adopted on my personal landline. With the > ringers disconnected.

Those who I know/expect/desire calls from I can route them directly to my extension, those others get the IVR. It works parallel to IP routing. I can go a few days without hearing my phone ring yet my logs are filled with spammers/telemarketing calls. Robo-dialers have no clue which extension a human may be at, and I've been doing this for over 15 years with great success. With a digium wildcard, this can work for POTS lines as well.
