Call blocking is important for any business hoping to deal with the distractions and time waste caused by solicitation and telemarketing calls. Call blocking can also apply for outbound calls to prevent wasteful employees practices of company's resources and money.
The simplest call blocking is defined by specific numbers you enter in Telebroad's PBX administration interface. It helps you get rid of unwanted repeat offenders originating from the same numbers. Other call blocking choices allow you to block calls from entire area codes, prefixes, or number sets (minimum 6 digits).
Call blocking can be applied for the entire inbound traffic as a whole, or on a user by user basis.
For inbound calls, you can also alternatively sign up to the National Do Not Call Registry, making it entirely 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.
You can also track the outbound calls employees make in the PBX comprehensive calls logs (which can be sorted and filtered as needed) and enter select numbers in the management interface, blocking unwanted outbound calls. For outbound calls you can choose to block all costly international calls or directory assistance calls (411).
Call filtering is a more advanced type of call blocking where calls are filtered 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 contact 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 to lose potential clients from certain area codes or markets. Rules can be prioritized, emphasizing some over others, and creating complex filtering scenarios.
Lastly different rules can have different routing, where instead of actually blocking a call you route it to a certain destination - a mail box, a specialized agent, or the automatic attendant.
