Note 1: Call Completion towards innovaphone fails due to a missing CONNECT ACK ISDN message. The Omni PCX does not send this message as reply to the prior CONNECT with ccnrRequest.rr. Call Completion towards the Omni PCX fails, because innovaphone disconnects the call through which it received the ccExecPossible message before it sends out the ccRingout call.
