Hello.. I rolled out a bunch of SPA122 for my customers.. A few of them are reporting that they are getting echos on the caller side. Caller is reporting they can hear a delayed echo of there own voice. I've made sure echo cancellation is on and I've adjusted the FXP values that were recommended for this issue and the echo is still there.. I've decided to upgrade the firmware on these SPA122 to see if this would help but when doing so the choose file button is grayed out and I'm unable to upload the .bin firmware file.. I've tried multiple browsers.. there is an old thread in here with a solution but when I click on the link for the solution the link is broken.
Current firmware is 12.1.. I really would like to avoid factory setting all of these SPA122's
Thank you!
