I Have Linksys ata voip adapter with caller id filtering built in so i can filter all the unwanted phantom callers and telemarketers etc. It also has the Hang up option , the out of service ,send to mailbox and more built in,, i also don't allow international calls turned on,,i can change my caller id if i want to remain hidden for a certain reason. Its great to have those options. It can be annoying getting those calls like when i am under my vehicle serving it.
