Hi All,

I'm having issues with inbound call which bridges to an external SIP handset, gets busy and then hangs up. All i want is for the A-leg not to hang up when the bridge fails (/completes with result BUSY)

I am using ESL inbound and my event driven script will answer the call, set the ringback to a UK tone, play 1 second of silence, then issue the bridge as follows:

{ignore_early_media=true,continue_on_fail=true,park_after_bridge=true,hangup_after_bridge=false}sofia/external/200010006@sipserv.net

Once this has all gone through everything works correctly when the user is available. When busy however the calling channel is ending the call rather than returning to park. I had anticipated collecting the CHANNEL_EXECUTE_COMPLETE event for the bridge command, reading the variable_DIALSTATUS for "BUSY" and then playing busy tone but it is just hanging up.

Is there a clean way to resolve this? Even if its just setting the "busytone" equivalent of "ringback" that would probably do?

Any help would be appreciated, maybe i'm just misunderstanding "the proper way" to handle this event :)
