WWWT has developed its IP Voice Mail server, as part of the family of services that run on WWWT's SIP Application server. The IP Voice Mail is deployed in a SIP network and interoperates with other SIP servers and SIP User Agents.


The Voice Mail server combines a unique native IP architecture with an open standards approach to allow quick feature upgrades and enhancements that are not found in other voice mail systems.


The software runs on standard servers and requires no special purpose telephony interface hardware, providing cost effective and easily up-gradable implementation and a winning ROI model.


Being highly scalable, WWWT's Voice Mail server architecture enables smooth migration from entry level to large scale users.

WWWT’s IP Voice Mail server has the ability to work with external OSS and provisioning system via API.


The provisioning system enables the following functions: Create /delete users, Mail Box Quota, IVR language, Pin number, f/w Voice message to e-mail

System Features

All system management and monitoring is done via the web. The monitoring service provides the Service Provider with on line information regarding the Voice Mail’s current activities.


A power reporting engine is used to provide a detailed picture of any aspect of the Voice Mail activities.


The reports can be produced in any one of these formats: Excel, HTML or PDF and provides an excellent management tool for the Service Provider’s administrator


Cluster Deployments & Redundancy

WWWT’s Cluster Architecture answers the need for a reliable and scalable system in the Telco market.


Cluster Architecture enables large scale deployments utilizing standard off- the-shelf application and storage servers.


The basic cluster is built with N+1servers and one local, fully redundant, storage server.


All data-bases are stored centrally, in one storage server.


The Voice Mail server is at the front end of the clusters and in case one of the servers fails, the other servers receive the calls.


Industry Standards

WWWT’s Voice Mail supports several leading industry standards including: SIP protocols, IMAP, LDAP and RDBMS for management /monitoring / reporting capabilities.


WWWT’s IP Voice Mail was introduced in 2000 and became part of industry interoperability and field deployments.


WWWT’s IP Voice Mail supports external Media Servers.
