[Freeswitch-users] Simulate a Collect Call behaviour

Hello All, I am in need to simulate a Collect Call behaviour for a particular case and I have tried Asterisk to do that but without any luck and I am wondering if FS can do that. Scenario: A calls B when B answers A hear an announcement (pre-recorded) and B hears another announcement. If B stay in the line after heard all the announcement the call is connected. I have found this ( http://wiki.freeswitch.org/wiki/Freeswitch_IVR_Originate#Answer_confirmation) but I am not sure if it can accomplish this scenario. I really appreciate any tips.
