Yealink SIP-T23G Echo after Upgrade to 3Cx V16

[SimonCC]

Hi

We recently upgraded to Version 16.0.910, which also forced a firmware upgrade of the Yealink SIP-T23G phones to 44.84.0.35

Since this point we started getting echo on all calls, the calling party can hear themselves back.

This only started after the upgrade. There seems to be some mention of a similar issue on the Yealink support forum http://support.yealink.com/faq/faqInfo?id=78

I have yet to change anything, but wondered if this is a known problem please?

Regards,

Simon.

We are having the same issue, have tried the steps described but it has made no difference.

Tried downgrading firmware manually to 44.84.0.15 and issue still persists.

Any ideas?

We had a little success, applying the recommendations from the Yealink forum, but not on all phones. Turning the volume down on the handset, seem to help a little.
