Having trouble pinpointing an issue we've been having with our Htek Phones after latest version of 3cx.
All of our HTEK UC924 Phones have been having call quality issues with the latest update / firmware. (Call audio is very faint or not able to hear at all or call starts fine and deteriorates)
It seems to only effect the phones that are routing calls through our SBC.
All remote locations using the same HTEK phones and STUN are working perfect.
We have a couple Yealink phones also running through the SBC and they have been working great same with calls through the desk client.
SBC is running 16.0.390
I've replaced the SBC running on a PC to a Raspberry Pi with no call quality improvement.
We have about 8 phones behind the SBC so I don't think its being overloaded.
