Would anybody know of a best practice document that I can refer to for both FoIP and VoIP to be configured on the same Voice Gateway? here is an example. We have 6509 cores with a ccm module that will have 3 PRI (Two for voice and one for fax) how would we go about for the config for our voice gateway to let voice be priority out as we don't want the outgoing faxes to get in the way.
