Retail service: Unified Messaging (UM)
With UM, voicemail, e-mail and fax are gathered together into an electronic mailbox with one unique number. The receiver can decide how and when to collect the message. For example, voicemails and faxes can be displayed in an e-mail and e-mails can be listened to.

Wholesale service: Electronic Messaging Connect (EMC)
EMC enables the 084 numbers of a service provider to be dialled by end users on KPN Telecom's fixed network. This means that the service provider is able to offer its UM services to all of KPN Telecom's fixed subscribers.

084 numbers are accessible from:
- KPN's fixed network (with EMC)
- the networks of Dutch fixed and mobile operators (with the additional service Premium Transit)
- abroad (with the additional service Incoming International Telco Terminating)

084 numbers:
- are not portable
- have 10 digits
- cannot be dialled with carrier (pre-)select
