Yealink T58A - audio issues - constantly change volume in call


I’ve seen that this device isn’t in this list EPM-Supported Devices - PBX GUI - Documentation, but it just use SIP, I’ve opened a ticket with Yealink sent any kind of log, they got it open with R&D by 2 month right now.

This is what echo test audio appear from wireshark:

I’ve tried this device on 3 different freePBX and make the same on all of them (with asterisk 11, 16, 18)

I’ve tried PJSIP enabling the JITTERBUFFER in dialpan, no luck.

Is anything I can try (other devices works fine)?
Thanks, BR
