Outbound audio disconnects after 2 seconds

[carl]

Suddenly, my outbound audio disconnects after 1-2 seconds on all providers . Router settings unchanged. Any ideas?

Now it took about 30 minutes to reboot the unit. I sent a warranty claim to the CS, but no response yet. Good thing I have my cell phones .

It seems that the problem is this time with the 2 months old V tech phone system- another company with e-mail CS . Since the 30 day period to return passed , I am stuck. (Lesson here : buy stuff from Costco, you can bring it back during the warranty time except TV and computers).
There might be still some issue with obi but I have to take care of the phone issue first.
