Get Started

You can test our sample app here: Download VP Demo app. The sample app allows you to test the Walkie Talkie function. Input any user ID and company name. Devices should have same company name to be able to communicate, but different user ID.

If you enter the channel with the same user ID in the same company, the previously entered device using the user ID will be out (exited) from the channel.
