Re: Another problem is with Number withheld
As an ex PABX programmer I can tell you that it would normally be handled by having sales groups outbound CID sent to the group inbound DDI and most individual phones within an office that were allowed inbound calls would be allocated DDI's. With CLI, whichever agent picked up the phone would register who the caller was and proceed as normal. I'm sure that since me leaving the industry CMS have become even more integrated and so would only be a problem if the caller was withheld.
