Call blocking is important for any business coping with the nuisance and time waste caused by unsolicited telemarketing calls, many of them generated by software robots. Call blocking can also apply for outbound calls to prevent employees from abusing the company's phone resources.
Call blocking is ahcieved by using the Filtered Forwarding feature from the admin protal. It can be set up for specific numbers to get rid of repeat offenders originating from the same numbers. A more advanced choices allows you to block calls from entire area codes, prefixes, or number sets (minimum 6 digits).
For inbound calls, you can also sign up to the National Do Not Call Registry, making it illegal for some telemarketers to call you. After you register your number, telemarketers have 31 days to stop calling you. Afterwards they are subject to heavy fines if they keep calling you on the number you registered.
Some of the phones we sell and support also have a feature to automatically block incoming anonymous calls, some of which may be unsolicited. Refer to the specific user guide for your phone on this support portal for more information.
You can track outbound calls and block select numbers in the admin portal. You can also choose to block all costly outbound international calls or directory assistance calls (411).
Call filtering is a more advanced type of call blocking where calls are blocked according to specific rules. It allows for schedules setups where the filtering applies only on certain hours or days. This can be useful, for example, if different shifts or workers deal with different area codes or countries.
Call filtering rules can also let some calls be accepted in situations where, otherwise, regular call blocking would have applied. For example when an incoming number already exists in a user's address book, call filtering would allow it even if the area code for the number is blocked.
By combining several rules you can create lists of approved numbers that meet certain criteria to make sure you don't lose potential clients from certain area codes or markets. Rules can be prioritized, emphasizing some over others, to create complex filtering scenarios.
Lastly, different rules can have different routing options where instead of actually blocking a call you route it to a certain destination — a voicemail, a specialized agent, or the automatic attendant.
