Blacklist of incoming calls. “It is a device responsible for blocking incoming calls to the phone. It is capable of blocking specific phone numbers, prefixes, entire area codes, anonymous calls and calls with Phone Number List caller ID blocker.” Blacklisting of outgoing calls “It is a device responsible for blocking outgoing calls from the phone.

They are established according to the priority criteria established by the company in order to control the volume of incoming calls. In this way, with virtual PBXs we can automatically redirect calls to the appropriate departments or services for greater efficiency. In addition, it allows us to identify the origin of the incoming number and restrict it in case it is an unwanted number. At we have a virtual PBX with a wide variety of filters and functions that allow companies to filter and identify each call to give it a personalized treatment. For example, we can apply different outgoing call blacklists to each PBX customer, so that some can make calls that generate extra costs and others cannot, depending on the list applied. Apart from the blacklist filter, we have other filters that are in great demand:
