Grandstream BT100/201 No Audio either way

Hi Folks,

I have rearranged codecs on the GS checked the dtmfmode (rfc2833) on the GS and trunk. Can I look in the debug and what should I look for or should I be checking another path? My other voip phones work fine. My router has spi turned off and no SIP ALG

Thank you.

Overnight something propagated or changed…? I did not make any change that affected the audio in any real time. Woke up this morning and I have two way audio on all my GS phones. I would love to know what happened.
