Well, we have H.323 setup now running 12.4.9T inorder to get call
preservation, which works pretty well. I don't think that we'll be
switching to MGCP / H.323 fallback precisely because we don't want to
drop calls.
I've asked our Cisco SE if using SIP trunks will give us the benefits of
caller name delivery _and_ call preservation in case of WAN failure.
He's still getting back to me.
