Mitel MiVoice Business/MCD/3300 / Audio drops on LAN calls

« on: March 19, 2019, 11:39:54 AM »

We are having an issue where audio will drop for 3-5 seconds periodically during an IP phone to IP phone calls. The call will stay up, just a period of silence. We have 6920 phones and the 3300 controller.

What I have noticed is that if I change the switchport access vlan (not the voice vlan that the phones are using) to a less busy vlan that the drops do not occur. These drop can happen within the same switch, we do have QoS enabled.

I think these phone might use ARP as a keep alive an suspect they cannot keep up with the amount of traffic on the busier vlan.

Any thooughts?

Mitel MiVoice Business/MCD/3300 / Upgrade 6920 Firmware Remotely

« on: March 07, 2019, 08:38:16 AM »

Is it possible to upgrade the firmware on a single minet 6920 01.03.00.112 for testing purposes? I know I can statically assign the TFTP server address on a phone if I am at the phone. But is there a way to do that remotely?

Mitel MiVoice Business/MCD/3300 / Voice Quality Statistics report

Hi, can anyone explain the Voice Quality Statistics report? I don't understand how there can be a zero in the packet loss column but a 204 in the Packet Loss Max. Burst column.
