Hi,

I'm having some issues with a Sip phone T38G with two EXP39 attached.
The phone is working well, but, all of a sudden reboots. It happens once or twice a day. One more issue I'm having is that, and also happens sometimes, when i'm answering a call, lifting the handphone, the call gets on speaker.
I have seen the asterisk logs, the phone logs and I cant find any reason to this problem.

The firmware version is: 38.70.1.33
I also downloaded the config file and the syslog from the phone.

Appreciate all the help.
Thanks

Hi Michael.

Thanks for the answer.
I'll try that and let you know if it worked.

Thanks

Any update to this? I have a customer with a lot of these phones and they are having the same problem when answering the phone and the audio coming out of the speaker and not the handset
