My Extend Home device is a Grand Stream HT801. Grand Stream released a firmware update yesterday, 10/13/2021, for the HT801: v188.8.131.52. My Extend Home is way behind: v184.108.40.206.
How may I upgrade the firmware?
Since its purchase, I have had many issues with the Extend Home - in particular, it is not reliable because most times it sends incoming calls directly to voice mail but never blinks the voice mail light. My goal is to get the device up-to-date and see if that helps.
