Sandbox phone numbers for inbound calls testing

Buying real phone numbers for testing purposes isn’t cool, what’s cool? Sandbox phone numbers – they are very cheap (they aren’t free just to let you test withdrawals as well) and you can buy a lot of them. So how does it work? If we go to Control Panel -> Phone Numbers and use the switch on top of the page to show sandbox test numbers, then the list will appear (see image below):

Sandbox numbers

After test number has been bought it becomes available in My Numbers and can be assigned to particular VoxImplant application.

Sandbox number

After test phone number is attached to the application, application rules should be adjusted to forward calls from the number to specific VoxEngine scenarios. And the last but no least thing is how you can call this sandbox number. We offer number of access phone numbers in different countries:

  • +19292240694 (United States)
  • +74993504126 (Russia)
  • +48223970842 (Poland)
  • +81345790139 (Japan)
  • +390694500414 (Italy)
  • +97243720980 (Israel)
  • +420228880669 (Czech Republic)
  • +14388002812 (Canada)

  • +61283104145 (Australia)

Call one of this phone numbers and enter your sandbox phone number as an extension, then the call is will be forwarded to your application.

Voicemail detection

Voicemail IconThere is number of different scenarios when you would like to know if you’ve reached voicemail or live person during the call, and if voicemail was reached it’s a good thing to know when you can play a pre-recorded voice message to leave it in the inbox. Keeping in mind that VoxImplant is a perfect choice for building power dialer or predictive dialer app it makes a lot of sense to offer this functionality to our developers. We’ve implemented both voicemail detection and voicemail tone detection algorithms to let developer control the call flow on VoxEngine scenario level.

Video Conferencing

Video Conference

A lot of people use video conferencing functionality in Skype, but Skype is standalone application and it’s hard to integrate it with your own service. VoxImplant lets developers embed similar functionality into any web or mobile application. This tutorial will explain how to build video conferencing service with dial-in/dial-out functionality (to connect PSTN participants) and browser-based client application using WebRTC capabilities and VoxImplant.
