MiaRec supports a deployment in virtual environment. Following virtualization products are supported:
| Virtualization product | Supported? |
|---|---|
| VMWare ESX/ESXi 4.1 | Supported |
| VMWare ESX/ESXi 4.0 or older | Not supported (see note 1) |
| Microsoft Hyper-V | Not supported (see note 2) |
Note 1: VMWare ESX/ESXi 4.0 or older versions do not support USB devices. Support of USB devices is necessary because MiaRec stores licenses on HASP USB dongle. Starting from version 4.1 VMWare ESX/ESXi supports USB devices.
Note 2: Microsoft Hyper-V doesn't support promiscuous mode for virtual network adapter. Because of this limitation, port mirroring doesn't work properly and MiaRec doesn't receive voip call traffic from IP phones.
MiaRec leverages port mirroring function on the network switch. A virtual network adapter should be switched to promiscuous mode, otherwise MiaRec will not receive network packets from IP phones.
To configure promiscuous mode on VMWare ESX/ESXi:
Note: It is highly recommended to allocate a separate physical network adapter solely for call recording purposes (port mirroring). And enable promisuous mode only on that adapter. Otherwise a network performance of other virtual machines may degrade when promiscous mode is enabled on their virtual network adapters.
Especially this is recommended when other virtual machine has running DNS or DHCP services. These services work incorrectly when network adapter is opened in promiscuous mode, and this causes a distortion in audio on IP phone side.
