The question is. There are telephones "A-G", telephone "W", telephone "Z".
It is necessary to make it so that when calling from any phone "A, B, C, D ... and so on." phone "W", phone "W" called phone "Z". those. phone "Z" should determine to see that "W" is calling him, and not "A,B,C ..."
How can this be implemented?

If we are talking about mobile (cellular) communications, then you can contact the operator: each operator has a service, often referred to as MVPN (it is positioned under this name, although the implementation of the scheme is very dynamic and can be implemented by the operator at different levels of the network, building logic in the same CAMEL Gateway , in which the logical processing and routing of calls according to signs and conditions takes place). The bottom line is that the processing of incoming and outgoing calls is carried out at the Intelligent Network level using the INAP / CAMEL protocols, with which you can easily configure what you write about. The only condition: as a rule, services of this type are not provided to individuals - check with the operator.

It is possible on Asterisk. If not, then for example, for free
Virtual number for free W
In the sip settings, specify a fixed number for outgoing calls to this number and forward it to Z.
