Grandstream GXP2100 Series Security Q&A Session

Question 1: Firmware is constantly coming out. What is the firmware that is suggested to get all of these security settings capable?

Answer: The live demo today in the webinar is the beta version. But everything you see in the demo is available on the official firmware version. The latest firmware version has them all.


Question 2: I did an update to a site with 107 GXP21XX phones and when it asked for password change, I changed it but then it locked me out of the phone. It would ask for a password change every time and I couldn’t get around it.

Answer: This is not related to phone bugs, it can be related to your browser. Sometimes you changed the password and the browser still has the old information. I suggest you clear the browser cache or try using a different web browser.
