Hello, When using Outbound ESL in async full mode and executing a API command like uuid_transfer or uuid_bridge using bgapi, which channel event is generated to notify the command execution completed? For dialplan applications it is the CHANNEL_EXECUTE_COMPLETED event. That I know. All I got is this: Command Executed: uuid_transfer 563c9750-64cc-11e4-8cd8-4fc1451152d2 -both park_extension XML park_ext Bgapi returned an ESLevent: { "Event-Name": "SOCKET_DATA", "Content-Type": "command/reply", "Reply-Text": "+OK Job-UUID: ede6c869-0bfa-4e07-8490-04973b6ba971", "Job-UUID": "ede6c869-0bfa-4e07-8490-04973b6ba971" } However, a channel event named SOCKET_DATA did not show up when listening for channel events using the RecvEvent method. What I'm trying to do is use bgapi or sendMSG to execute an application/command, and use the RecvEvent method to wait for a channel event that indicates the application/command completed execution. So if I were to use the playback application, I'd send it using the SendMSG method, and use RecvEvent to wait for the CHANNEL_EXECUTE_COMPLETED event containing the UUID set for this playback. This works fine for dialplan applications but I don't know which event to listen for when using api commands. I hope someone could point me into the right direction. Regards, Grant
