The BELCOM-ISDN "PLUS" PABX system, when the telephonist is busy, answer the calls with welcome greetings. If the call continues in the waiting queue, other different messages will be delivered. The client doesn't feel abandoned and the company can use these messages to transmit commercial values. The client can call the desired extension directly, without passing through the telephonist through the function Automatic Assistance. Even if the client disconnects, the call can be retrieved through the exclusive function to Retrieve. With this service, an image of an organized company with quality is transmitted.
