Hi, I’m running freeswitch version 1.8.1. In the log files, I saw a lot of [ERR] too many stacked extensions. It happens when freeswitch is trying to bridge a callcenter member to agent. I don’t know how to handle it. Could you please give any advises? 55791bf8-30bb-11e9-a4fd-7125b8df8c7a 2019-02-15 08:47:56.419673 [DEBUG] switch_ivr_bridge.c:1063 sofia/internal/137095@10.20.86.100:5060 CUSTOM HOLD 55791bf8-30bb-11e9-a4fd-7125b8df8c7a 2019-02-15 08:47:56.419673 [DEBUG] switch_core_state_machine.c:662 (sofia/internal/137095@10.20.86.100:5060) State CONSUME_MEDIA going to sleep 55791bf8-30bb-11e9-a4fd-7125b8df8c7a 2019-02-15 08:47:56.419673 [ERR] switch_ivr.c:902 Error sofia/internal/137095@10.20.86.100:5060 too many stacked extensions 55791bf8-30bb-11e9-a4fd-7125b8df8c7a 2019-02-15 08:47:56.419673 [ERR] switch_ivr.c:902 Error sofia/internal/137095@10.20.86.100:5060 too many stacked extensions 55791bf8-30bb-11e9-a4fd-7125b8df8c7a 2019-02-15 08:47:56.419673 [DEBUG] switch_ivr_bridge.c:1744 (sofia/internal/137095@10.20.86.100:5060) State Change CS_CONSUME_MEDIA -> CS_EXCHANGE_MEDIA 55791bf8-30bb-11e9-a4fd-7125b8df8c7a 2019-02-15 08:47:56.419673 [ERR] switch_ivr.c:902 Error sofia/internal/137095@10.20.86.100:5060 too many stacked extensions 55791bf8-30bb-11e9-a4fd-7125b8df8c7a 2019-02-15 08:47:56.419673 [ERR] switch_ivr.c:902 Error sofia/internal/137095@10.20.86.100:5060 too many stacked extensions 55791bf8-30bb-11e9-a4fd-7125b8df8c7a 2019-02-15 08:47:56.419673 [DEBUG] switch_core_state_machine.c:584 (sofia/internal/137095@10.20.86.100:5060) Running State Change CS_EXCHANGE_MEDIA (Cur 2 Tot 4919) 55791bf8-30bb-11e9-a4fd-7125b8df8c7a 2019-02-15 08:47:56.419673 [DEBUG] switch_core_state_machine.c:653 (sofia/internal/137095@10.20.86.100:5060) State EXCHANGE_MEDIA 55791bf8-30bb-11e9-a4fd-7125b8df8c7a 2019-02-15 08:47:56.419673 [DEBUG] mod_sofia.c:645 SOFIA EXCHANGE_MEDIA XML: <condition field="destination_number" expression="^(31\d{4})$" > <action application="set" data="dialed_extension=$1"/> <!-- hangup after successful bridge to agent --> <action application="set" data="recording_follow_transfer=true"/> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="say_agent_first=1" /> <action application="set" data="bridge_pre_execute_aleg_app=lua"/> <action application="set" data="bridge_pre_execute_aleg_data=broadcastAgent.lua"/> <action application="set" data="call_type=q" /> <action application="bind_meta_app" data="4 ab s execute_extension::att_xfer XML features"/> <action application="callcenter" data="$1"/> </condition> </extension> Thanks Ceniy Mei
