   FastIVR for Cisco - Cisco Simulator

Cisco emulation environment for Tcl IVR script development


Cisco Emulation Environment

Effective August, 10, 2011, Fast IVR for Cisco has been discontinued. Fast IVR for Cisco provides a complete Cisco environment simulation on a PC. Fast IVR for Cisco is a powerful tool for generating and evaluating TCL scripts for Cisco VoIP-enabled gateways. Fast IVR for Cisco enables the telecom operator to execute and evaluate Cisco TCL IVR scripts locally on a workstation, using FastIVR Cisco simulator, without the need to remove an expensive piece of hardware from production network system. Moreover, Fast IVR for Cisco tool is infused with deep experience in developing and implementing high-capacity flexible Interactive Voice Response programs and strategies - it is the most effective and innovative tool available for customer care, contact, and communications.

Our IVR solution is an essential component in the marketing efforts of top-tier companies in the growing VoIP space. Our IVR solutions offer telecom operators with state-of-the-art technology, so that they can provide superior customer service and very flexible products to their expanding customer base.

FastIVR for Cisco provides a complete Cisco router environment simulation. It emulates Cisco terminal, accepts all commands supported by the actual Cisco hardware, and provides exactly the same responses as a real, non-simulated Cisco would provide.


  • Cost effective: positive ROI results in just a few months of installation by many of our customers
  • Exact Emulation: precisely simulates a Cisco VoIP gateway
  • Platform-independent: written in TCL, so that it is fully interoperable with any UNIX, Solaris, Windows or Macintosh

Even though Cisco TCL IVR API is made basically for IVR, it also accesses Cisco call control, including cli, cld (ani, dnis) processing, call routing etc. That overpasses Cisco IOS limitations and lets you easily customize your VoIP network functionality.

Compare Developing IVR Scripts With and Without the FastIVR for Cisco

IVR script development without FastIVR

IVR script development with FastIVR

IVR script development: native Cisco development vs. FastIVR Cisco Simulator

Typical process of developing/testing of Cisco IVR script

  1. Editing script
  2. Locking the script
  3. Uploading script to tftp server
  4. Reloading application in Cisco "call application voice load <name>"
  5. Placing a call over telephone line
  6. Repeat 1-5 in case of errors

with Fast IVR for Cisco, using Cisco simulator

  1. Editing script
  2. Testing script in FastIVR with Cisco router simulation
  3. Repeat 1-2 in case of errors

Who needs such a long implementation process, when Fast IVR for Cisco can be deployed in a matter of hours and achieves superior results?

  • Every company that owns a voice-enabled Cisco gateway and plans to customize the IVR system functionality benefits tremendously from our solution
  • Every VoIP provider benefits from introducing advanced, exciting, value added services into the VoIP network
  • Every training facility benefits from the knowledge of how to work with Cisco TCL IVR

FastIVR Visual Studio

FastIVR Visual Studio is a powerful application for generating TCL IVR scripts from a call flowchart created by the user in a chart editor.

FastIVR Visual Studio is in the development stage and will be made available in the 1st Quarter 2003.


  • Enables the rapid deployment of VoIP IVR
  • Eases the integration of FastIVR
  • Allows for the visual design of IVR using drag and drop feature
  • Creates high-capacity, flexible IVR Programs
