Additionally, some WiFi networks may require an Internet firewall configuration to fully support Voice over IP services. Contact our support department at - Criticomms-support@criticomms.net - for help with WiFi integration.

No, our application works with most smartphones on the market: Android, iPhone, iPad, Android Tablet or Windows PC. If preferred, the application can be used with “rugged” or “purpose built” equipment in conditions where a shock-, dust- and waterproof device (IP68 / 69) is required. For this, we recommend the RugGear equipment that has been certified with our application (see Solutions)
