PCS Mobile Application Setup Checklist
System Requirements
Infrastructure: Asterisk 1.8
Browser: Chrome (Version 63.X or higher), Firefox (Version 57.X or higher)
Bandwidth: 8 Mbps – required, 10 Mbps – recommended
Hardware: A microphone and speaker (internal or external) is all that is required to connect to the PCS UC. Optionally, an external microphone or headset is recommended for better sound quality, and a basic webcam (internal or external) is required to show yourself in video meetings. A wired network connection is recommended for the best UC experience, but a strong wireless connection will work as well.
Corenexa UC/Mobile does not allow shared logins for multiple people to log into the same account. This will cause conflicts with calling and messaging on the clients.
