Poor Audio Quality with .82 Firmware


(Ruler2112) #1

Out of the blue, we began experiencing the issue described at https://community.freepbx.org/t/sangoma-phones-require-a-weekly-reboot/71721 - phones would just start behaving like they had a process running away, consuming 100% of their CPU time. It only affected the s500 & s705 phones, which were both running the .72 firmware.

Seeing there was a fix in .78, I applied the latest revision - .82 as of this post. I immediately began receiving complaints of poor call quality. People sounded tinny, the first few seconds of the call were extremely quiet, customers saying they can’t hear us, etc.

I am about to go up and revert these phones to .79 or .78 to hopefully resolve the issues, but wanted to report it. Worst case, I’ll put .72 back on & they can live with rebooting their phones when it happens…

Is anyone else experiencing problems like this with .82 ? Is there a known easy way to trigger a reboot of the phone from the server command line? (My thought is to write something to interface with the phone’s GUI, but am hoping there’s a tool already available. If I could schedule the phones to reboot themselves say 2 hours before people get here, it should eliminate the issue with .72…)

Firmware version .78 also had ‘crackling’ audio & no audio at the beginning of calls for 1-3 seconds. I put .72 back on & call quality is again good.

Now to see if I can find a way to trigger a reboot of the s500 phones in an unattended way to eliminate the other issue…

There were audio related changes made in both .73 and .75. Did either one of those introduce it for you, and not specifically .78 or .82?

Hi @RealRuler2112

I recommend you open a phone hardware support ticket for this so the findings can be escalated properly
