I support a small business using the UC320 and 12 SPA514G IP phones. Seems like they too have that symptom...Call will come in and the receptionist will answer the phone and she can hear the caller but the caller cannot hear her.
It takes either a modification to the system (say a user name change) and save it or a reboot will clear things up.
In addition, when the AA is on after business hours it sometimes doesn’t pick up the calls.
This is sporadic and is very annoying. Can anyone offer any suggestions?
Thanks. Marc.
