We recently set up a VSX 7000 for our company.But we can only receive audio from far side and can not send any audio out.All port from 3230 to 3250 already opened and video work fine(send/receive).Did we miss anything need to setup for sending audio out??

If you can hear yourself - you VSX 7000 is ok and probably it is network problems (NAT, Firewall, etc). If you can't hear yourself - something wrong is with your VSX or mic or cable ...
test your mic at System > Diagnostics > Audio > Audio Meter
