SPARK IP Media Server

A Unified Media Platform with Advanced IVR (Interactive Voice Recognition) & Media Deployment Capability

Wavenet's Spark platform includes a suite of tools that enables CSPs and mobile operators to offer superior customer service experiences while reducing cost, and offering the opportunity to generate additional revenue through the following services:


The Spark IP Media Server platform is a pre MRF media server built using Open standards and can be easily integrated into even evolving networks such as IMS networks making it future-proof and facilitating Operators to extract greater returns on investments.

  • Consolidated service platform for real-time media processing and DTMF detection
  • VoiceXML v2.1 and CCXML v1.0 Compliant
  • Full W3C standards support
  • Text-to-speech (TTS) with MRCP 2.0 support
  • Inbound and Outbound call handling capability
  • Web-based application and comprehensive reporting for in depth traffic analysis
  • Real-time logging and debugging
  • Multiple media codec support and passthrough

One platform, many voices

Spark platform can be used as a base for all types of voice applications supporting CCXML and VXML. Programed SOAP interface opens up the platform to external applications to offer higher-value services to the consumers. The Spark IPMS platform also supports the operation of multiple revenue generating applications.

RBT is a personalisation service offered by Operators to subscribers where the standard ringing tone is replaced with a song or audio clip

Voicemail service is a VAS offered to subscribers to receive recorded voice messages when they are unreachable

Missed call alert is a call completion VAS where users are sent a SMS about an attempt made by a caller to reach the user when away from the network.
A solution that facilitates users with insufficient balance to place a missed call to the call terminating party.
Collect call enables subscribers with low balance to request a call from another subscriber free of charge, provided the recipient accepts charges for the call.
Allows subscribers to leave a voice message to B party by dialing a shortcode instead of dialing B party direct. The B party will then be sent a SMS to notify about the voice message

Multi codec support

Multi codec compatibility facilitates integration with almost any Operator voice switch. The ability to transcode and support different media codecs allows the maximum usage of the available voice channel bandwidth and give a better quality experience to the end user. The supported media codecs (with transcoding) :

  • G.711 a-law
  • G.711 u-law
  • G.729
  • AMR NB

Advanced call control

Real time REST APIs allow for the receipt, initiation and forwarding of call control

  • Blind transfers – call control is passed to 3rd party and call leg can be terminated. This is extremely useful in real life situations such as customer care applications, where if a customer wants to, he/she can select option to speak to an agent and call can be transferred without prompting to go back to main menu.
  • Bridge transfers – call control is maintained within the system. However media is transferred to 3rd party but may be done as a copy. This is important in situations where control of call is necessary and option should be made available for reverting to former option.

The Future of Speech Synthesis - Text-To-Speech

Text-to-speech ( TTS ) is now fully supported to allow greater options to gather inputs from callers apart from traditional input methods such as DTMF. The connectivity to external web servers for services e.g. over MRCP to communicate with external speech servers for TTS services.
