The feature to block certain incoming calls can be a boon when you want to block out calls from telemarketers or other solicitation calls which take away a chunk of your valuable work time. With the advent of VoIP, several such features have helped people streamline their work day even better than before.
The majority of businesses and individuals have switched to VoIP for seamless, cost-effective, and user-friendly communications. VoIP, or Voice over Internet Protocol, enables making and receiving calls using the Internet, rather than traditional phone lines. This has helped in saving costs related to installation charges, hardware expenses, maintenance charges, etc. It has also reduced long distance and international phone calling rates. Also, it has increased employee productivity by enabling them to take and receive calls on their cellular phones routed from the main business phone number, so they can continue their business transactions even when travelling or are telecommuting from home or visiting another location or branch of the business. It has also helped businesses cut down significantly on expenses related to business meetings by enabling employees to meet each other face to face wherever they might be, through VoIP video conferencing, without having to physically travel anywhere.
With VoIP call blocking, you can take VoIP call benefits to another level. Often times, the work flow and concentration is disrupted because of the frequency of unwanted calls from various sources, such as telemarketers. If a number is unknown, it can be blocked either through the provider or the software. The calls that can be blocked this way are numerous, from local calls to international calls to long distance or even VoIP callers. You can even block calls coming from a specific area code or sets of numbers with specific prefixes. You could also block calls from a fax broadcaster or an automated dialer. With a scheduler built in, calls can also be blocked or routed during a specific time of the day, and this can be configured to automatically launch on a daily basis or for a one-time basis.
Blocked calls can either be totally rejected (callers get a busy signal) or be routed to your voicemail depending on their importance. You also have the option of adding certain area codes or prefixes to your Invited list so that only numbers originating from specified area codes or prefixes can call and reach you.
