External call filters

Residential External Filters can be assigned to DDIs to temporary forward calls to an external number or to avoid call from undesirable sources.

Filters Configuration

This are the configurable settings of Residential external filters:

Name

Name of the filter.

Black list

External origin will be checked against the associated Match Lists, if a coincidence is found, the call will be rejected immediately.

Unconditional Call Forward

Calls to DDIs using this filter will be forwarded to given external number.

Tip

Blacklisting has precedence over unconditional call forward. Calls from numbers matching associated matchlist won’t be forwarded, they will be rejected.

Attention

Calls forwarded by a filter will keep the original caller identification, adding the forwarding info in a SIP Diversion header.
