[Freeswitch-users] Hangup after bridge

[Mody, Darshan (Darshan)]

Hi

I find below documentation for hangup after bridge

hangup_after_bridge
BOOLEAN Controls what happens to a calling (A) party when in a bridge state and the called (B) party hangs up. If true the dialplan will stop processing and the A leg will be terminated when the B leg terminates. If false (default) the dialplan continues to be processed after the B leg terminates. This is checked after park_after_bridge<https://freeswitch.org/confluence/display/FREESWITCH/Variables+Master+List#VariablesMasterList-park_after_bridge> and transfer_after_bridge<https://freeswitch.org/confluence/display/FREESWITCH/Variables+Master+List#VariablesMasterList-transfer_after_bridge>.

In the below code within switch_ivr_bridge.c we are checking park_after_bridge transfer after bridge (highlighted). However we are not checking for hangup_after_bridge setting and hanging up the channel. Is there any reason for missing the check of hangup_after_bridge flag before hanging up the channel?

static switch_status_t audio_bridge_on_exchange_media(switch_core_session_t *session)
{
       switch_channel_t *channel = switch_core_session_get_channel(session);
       switch_ivr_bridge_data_t *bd = switch_channel_get_private(channel, "_bridge_");
       switch_channel_state_t state;
       const char *var;

       if (bd) {
              switch_channel_set_private(channel, "_bridge_", NULL);
              if (bd->session == session && *bd->b_uuid) {
                     audio_bridge_thread(NULL, (void *) bd);
                     switch_core_session_reset(session, SWITCH_TRUE, SWITCH_TRUE);
