RayBan Meta Audio Issues with phone calls.

Hello.  Perhaps a remedial question yet hoping for some input.  Newly purchased Ray Ban Meta Gen 2.  Connectivity between my iPhone 17 and glasses have been just fine BUT I am unable to now take a phone call.  It’s as if both parties muted.  I hear the call come in and meta tells me who the call is from but I’m unable to converse after answering.  Dead air.   I have already asked meta to unmute and it was followed by a tone.  Any help would be appreciated.  Everything had been working great until now.
