T58A - SIP Licence - no sound at all

[nlale02]

Hi guys,
I recently purchused Yealink SIP-T58A SFB, and than converted it to SIP, update and conversion went great, smooth.
I managed to get it registerd and all that good stuf, but the problem is, when i try to call someone, or someone trys to call me, no ring sound, or any sound, when i pick up a call, i can not hear guy on the other side, or the other side cannot hear me, speakerphone is also no good, headset is detected but no sound, i cannot connect bluetooth audio device, (i can connect my iPhone via bluetooth and can access my contact from Yealink), when i try sound recorder (preinstalled app on the phone) gives me error when i press record button. No sound on keypress of anykind, or when i press anything on the touch screen.

So guys pleas help me out, is the phone broken, or is it some kind of demo version.

Phone specs are :

Firmware Version
58.86.0.20
Hardware Version
55.2.3.0.1.0.16

Thanks in advance for your help.

Conversion issue, perhaps?
