Well my first issue that has come up is people are leaving voicemails, and the server isn't saving them. When you check it says none. Second, I have really bad feedback on the phones, IE. you can hear yourself talking when in a conversation with people. I have Cisco 7960g's a Audio Codes MP-144 gateway, and am running 3CX Phone System Version 3.1.2434.0, any help would be much appreciated, thank you.
