I have tested an upgrade to the last Firmware 220.127.116.11, but it does not work with my Epigy phone systems (no ring, no sound, ...)
I have to get back to the FW 18.104.22.168. Where can I find it, because actually is it not available or can you send the FW by email?
My ask is urgent, I have no phone actually.
I thank you for your return.
Yes the problem is Under investigation with the Ticketsystem.
