T38G Handset no sound

[markm3334]

Hoping someone can answer:

Just received two refurbed Yealink T38G's for a customer to test. Their system is known working - Cisco SPA phones work fine from same IP address and ethernet port, v14 Pro.

I can make and receive calls from the speakerphone, but the handset has no sound. Thinking I had a bad handset, I switched them. Thinking I had a bad phone, I switched that too. Provisioned or not, I cannot get sound out of the handset (other than a buzz....buzz....buzz, barely audible).

I checked the handset level in the web interface. Tried different firmware to no avail.

Do I just have two bad handsets or is there something obvious I haven't looked at?

Thanks in advance for your help.

Hi there,
I would think that the easiest way to check is to borrow a phone that is working and test but from the description it sounds like you have 2 bad phones. If the call is established and there is audio coming through the speaker then i would think the issue is with the handsets
