Besides, the service of Forwarding through the Voice Manager, the BELCOM-ISDN "PLUS" PABX system also offers another possibility for the user who has moved away from its extension to continue to receive calls. For that, it can program its extension so that the voice manager seeks the recipient of a call in the company through the external speakers or through the ISDN "PLUS" telephones. When hearing the request, the user can answer the call in the closest extension.
