No sound on SIP-T23P handset
We have a brand new SIP-T23P handset that when a call connects there is no sound. The outgoing ringing tones are heard when on speaker. Volume and mute buttons appear to be working OK (i.e. the volume is set correctly).

Firmware 44.80.0.80
Hardware 44.0.0.16.0.0.0

We've reset the phone to factory settings again to no avail.

Regards, AjN3806
