OS is Centos 5.7. Most recent GIT has same code. In switch_ivr_bridge.c on line 1474, we have the following lines of code: switch_channel_clear_state_handler(originator_channel, NULL); switch_channel_clear_state_handler(originatee_channel, NULL); switch_channel_set_state_flag(originator_channel, CF_BRIDGE_ORIGINATOR); switch_channel_clear_flag_recursive(originatee_channel, CF_BRIDGE_ORIGINATOR); switch_channel_add_state_handler(originator_channel, &uuid_bridge_state_handlers); switch_channel_add_state_handler(originatee_channel, &uuid_bridge_state_handlers); Is the call to “switch_channel_set_state_flag” a typo? Since it triggers an asynchronous flag change on the channel thread, and at least in the scenario when the asynchronous change immediately after the next “switch_channel_clear_flag_recursive”, the clearing of the flag will not do anything. Thanks in advance.
