Voicemail

Overview

The great majority of POTS subscribers want some means of taking messages when they’re not able to answer the phone. Network-based voicemail has been around for a long time, and generates useful additional revenues – but take-up rates don’t always reach their full potential. Often that’s because the service offering does not give subscribers much by way of advantages over traditional answering machines.

Enter next-generation network-based voicemail, which offers subscribers a wealth of unified messaging features to make their lives easier. With the ability to handle both voice and fax messages, options to forward messages to email, and a huge range of notification methods for new messages, subscribers need never miss an important message again. And with Live Message Screening, subscribers can even use network-based voicemail to screen their calls the same way they do with their own answering machines.

Migration to a next-generation IP-based voicemail system is the best way to maximize take-up rates for network-based voicemail services, generating substantial additional revenues while increasing subscriber loyalty by making available new messaging features that quickly become indispensable. The Metaswitch solution for Wireline Voicemail Evolution may be deployed with all types of legacy Class 5 switches.

Metaswitch has vast experience with next-generation voicemail, and has deployed hundreds of systems with wireline service providers at all levels of scale from a few thousand to multiple millions of mailboxes.
