Highly reliable service and a good quality reached Well accepted in the market Heavy investment for hardware and software in the past

New fundamental Voicemail Services are not visible
What is the next stage of communication?
Where are we going to?
Combine Voicemailand Email Message to
Unified Messaging Service
create a Unified Messaging Box (UMB)

Keep in mind ! Save the operators investment Save the reliability Add a new dimension to voice
messaging, but keep the customer‘s telephony interface
Every thing new?

Typical login time to Email server is 7 to 30 sec The .com world will accept this
Nobody will accept such a delay on a telephone interface
Voicemail Message and status information (e.g. you have „n“ new Voicemails and „m“ Emails incl. header information) must be presented without any delay
Customer Expectations I
Michael Möhlenhof T-Mobil;Systemtechnology 20.04.23
page:8
No customer likes to change his telephone number or his Email address
Subscriber will expect well known intelligent notification schemes for all types of messages
Customer Expectations II
Michael Möhlenhof T-Mobil;Systemtechnology 20.04.23
page:9
Messages will be primarily accessed via the appropriate interfaces Voicemessages at the telephone as
speech Faxmessages with a fax machine Emails with an E-Mail Client
(Computer), Web Mail To reduce the traffic between systems
keep messages local until requested on other media
Assumption for UMB product I
Michael Möhlenhof T-Mobil;Systemtechnology 20.04.23
page:10
Added value is generated by interworking functions as Listen to E-Mails when on the move Collecting voicemails when online
(less important) Unified overview over all messages
received
Assumption for UMB product II
Michael Möhlenhof T-Mobil;Systemtechnology 20.04.23
page:11
Existing features at the Voice interface must be available for the customer
Examples: „Notification Engine“ HLR-Interrogation before Outcall
notification (smart notification) Automatic identification of the
customer by CLI Existing user interface
Assumption for UMB product III

EMC: Enhanced Message Collector Flexible interface between Voicemail and
Email systems Interfaces three systems:
Voicemail system E-mail storage (EMS) Large directory engine (LDE)
Technical solution: EMC
Michael Möhlenhof T-Mobil;Systemtechnology 20.04.23

All parts of the concept should be based on open standards A candidate could be IMAP 4 for interfacing VMS/EMS
POP3 may be used instead but raises some security problem does not allow for intelligent management of the message
box
LDE accessed by LDAP (X.500)
EMC: Open Interfaces

Internal routing of messages Transmission of Emails to a text to speech engine
at the VMS Transmission and conversion of Voicemail to
Email Systems in standard audio format like *.wav)
Telefax conversion to *.tif Initialization of the notification functions of the VMS
EMC Interfaces via IMAP4:

Large Directory Engine used for Administration interface Special secured storage of Log-ins for
EMS and VMS Customer address book etc.
Note: Password entrance of EMS defined by
ISP VMS Entrance secured by CLI / SIM or
password
Large Directory Engine:

All telephone operators have a voicemail system Development of new VMS Services fades out Investments should be saved Go internet
Summary
My mission: Bind the worlds use EMC concept
