IP IVR Calling card module:
The IP IVR module extends VoipSwitch of the whole set of services that utilizes voice interaction with users. The IP IVR version for Calling cards services is sold separately as a module. The IP IVR for other services is the part of the main package (VoipSwitch platform).
Main calling cards IP IVR scenarios:
- Two stage dialing calling cards (PIN or Caller ID/ANI authorization)
- One stage dialing with IVR (PIN or Caller ID/ANI authorization)
Examples of the additional IP IVR scenarios:
- Max call duration announcement
- Actual balance information
- Last minute (or any other defined period) before the call end warning
- Recharge by PIN
- Support number and others.
The IP IVR can be used with any VoIP equipment that is compatible with SIP or H323 protocol. Also it supports DIDs (SIP or H323 trunks). Thus, the access number for example for Calling cards can be implemented by using DIDs rented from a provider (instead of owning a PSTN gateway). In this scenario DID or DIDs are delivered over Internet directly from DID provider to VoipSwitch.
The IP IVR supports following Codecs: G723.1, G729, G711, GSM, G722. The voice prompts are stored in already compressed format what makes the system robust as it does not have to convert the prompts while realizing the IVR procedures.
The IVR scenarios as well as voice prompts are customizable. It comes with predefined scenarios that can be found useful in different applications. Also the new scenarios can be built by system administrator using XML scripting language.
The system is multilingual by default there are several languages uploaded, for example English, French, Spanish, Arabic, Hebrew and many others.
For professional voice prompts for the IVR we recommend GM Voices. Below are some samples:
