We are running freeswitch connected with a sangoma A101 card to the PSTN. We have an application that is connected to the event socket to control incoming calls.
When bridging a call to an external number, I set the profile variable "destination_number_ton" and put it also as option to the bridge command to have the variable filled in all channel events.   

sendmsg 
call-command: execute
execute-app-name: set_profile_var
execute-app-arg: destination_number_ton=1
event-lock: true

sendmsg 
call-command: execute
execute-app-name: bridge
execute-app-arg: {calltype=FORWARD,destination_number_ton=1}freetdm/1/a/XXXXXX
event-lock: true

In this scenario everything works fine, the type for the Called Party Number is set correctly to "international".

For another scenario I need to originate calls with bgapi function like:

bgapi originate {origination_caller_id_number=XXXX,originate_timeout=20,origination_uuid=7a1093b5-4225-4a99-b3dc-bb4254217e4,destination_number_ton=1}freetdm/1/a/XXXX &park

event if I set the profile_var destination_number_ton, it's not "transported" to the ISDN layer. In the ISDN trace I can see that the number type of the Called Party Number is always "unknown".

    70 10 81 34 39 32 32 31 34 30 30 36 37 38 33 31 30 31 ] 

How to can the destination_number_ton be set when originating a call via bgapi?

Thanks
