Hi,

We have a T28P with three EXP38 panels (all of them with their power adapter plugged) but, in some calls, the audio goes automatically from the handset to the speaker.
We have tried to change the T28P with the same result
It has the last firmware T28P: 2.72.0.75 EXP38: 5.17.0.0

What can we do?

Regards,

Hi,

This case is closed. I've made a deeply analysis and I can conclude that the issues our customer are experiencing are the same as those explained in post "T38G pickup handset doesn't answer the incoming call".

Thanks,

Hi Santi,

Thank you to support our phone.
