Service Description

BellSouth Simplified Message Desk Interface (SMDI) service is a switch feature that provides call data to a voice messaging provider and allows the provider to signal his end user.

With SMDI, voice-messaging providers receive basic information about calls made to their subscribers. Sometimes referred to as the backbone for voice messaging service providers, SMDI provides pertinent information for your voice messaging platform.

Data transmitted from BellSouth switch to VMS platform:
* Calling Telephone Number
* Called Telephone Number
* Reason for Call Being Forwarded (Busy/ No Answer).

Data transmitted from VMS platform to BellSouth switch:
* Message Waiting Indication - Audible or Visual

BellSouth ISMDI is the inter-switch version of SMDI. ISMDI takes advantage of the BellSouth CCS7 signaling network which is interconnected with BellSouth switches to transmit the information provided by SMDI, enabling you to offer voice messaging to multiple locations using a single data facility interconnection.

Whether your customers are located in big cities, small towns or single organizations, you can offer the voice messaging capabilities that meet their particular needs when you have BellSouth Simplified Message Desk Interface and ISMDI.

Benefits

With BellSouth Simplified Message Desk Interface service, you can offer end users the voice messaging services they ask for and expect, without breaking the bank.

When SMDI provides you with the reason for the call being forwarded, you can offer your customers customized greetings — one for busy and one for no answer. And with SMDI you can activate a message waiting indicator on subscriber phones, so that they know when calls are waiting. One service does it all.

And with ISMDI, you can provide wider coverage duplicating the SMDI-VMS configuration for each central office. It's the low-cost way to deliver voice messaging to tons of customers using a single interconnection point.
