I trying to connect an IPK II to a Right Fax PRI server, NEC tech support says unless Right Fax emulates a CO PRI it will not work, Right Fax says they have connected to everything as of right now it don't work. I have DID's pointed to virtuals fwded to an F-Route whichs routes them to a trunk group connected to a PRI card to their RightFax server. If I call the virtual it routes to the trunk group then drops. NEC says it's because they don't see the connection. Right Fax says they don't recieve the call but they say they don't have a way to monitor it. I've installed and serviced the IPK II for years but know nothing about this Right Fax any suggestions??? Customer is losing patience...
