recently installed 7200 and 7400 both using Samsung ip phones and sip trunking. unrelated customer same sip providers. the problem is no receive on second call (one way audio) secondary is poor speaker phone on conference calls. turning off MPS and switching to MGI the one way audio problem goes away the conference quality is still poor . any thoughts?

You will need to forward the MPS ports (UDP 40000-40127) as well as the MGI ports (UDP 30000-30031) to the OAS card.
Since you are using MPS you will need to look at changing the codec the IP phones use to G.729 as the MGI codec doesn't apply.
