Hi! every one
I have configured the ATA 186, perfectely, and can esteblish calls , but they r only one way, as I can’t hear the other praty voice, when the ring was bell on his phone, when he picked up the phone, and when he droped the call, as he was only geting my voice, and can’t send his voice towards me.
Please let me know what can be the possible causes of this malfunctioning on firstname.lastname@example.org
Thanks in advance.
