Is there any way how to fix mute button on Speak2 and Webex? Old Jabra speak used to work

I have deployed a linux server to ENCS with two interfaces "eth0" and "eth1" with IP addresses 10.0.10.132 and 10.0.10.133. There is an external router in my network as ERSPAN source generating traffic and configured to send ERSPAN to ip 10.0.10.133....

Can you advice how I can in NFVIS assign network model e1000 to my virtual machine? There is virtio only available. Thank you
