Hello. We have a MCD 4.2 at one of our sites. There is a single PRI servicing two separate tenants. Our objective is to bill back each tenant based on their LD usage. We have Prairie Fyre and accounting codes but we require a simpler way to separate the billing between entities. We would like to route all LD calls for one tenant over our IP/XNET trunks and out another PRI entirely. It seems Class of Restriction would do this..how would I setup the COR to ensure that the long distance calls go out another PRI and retain calling party number while at the same time sending all local calls out the local PRI trunks? thank you
