FXO hookflash / conferencing - CM 7.1


I'm running into an issue 7.1 that seemed pretty easy at first, but I'm hitting a wall now. We have a remote site that had poor Internet connectivity and decided to go with an 881 with local FXO resources and H323 back to the CM and a 7960 locally. The lines were ordered by the customer with call-waiting and caller-id on the call-waiting line. The issue is with inbound call-waiting and conferencing, the customer can hear the inbound call, but cannot pick it up or receive visual indication. With CME, you could implement the FLASH softkey and simulate the POTS behavior. TAC has directed me to the following bug / feature request that has existed since 3.1(1) . As for the conferencing portion, does CM also have problem initiating a three-way call (TWC) using an FXO line? It seems I can make an outbound FXO call and then conference in an on-net call, but I can't make two outbound calls.
