[Freeswitch-users] how to: get session variable after api_hangup_hook

Session is one of the parameters that get passed to API calls. If the API was invoked by a session, and not out of band, like form the console or event_socket, or any other way to invoke it, the argument will not be null. You can then get variables from the session handle just like you would do anywhere else.

Subject: [Freeswitch-users] how to: get session variable after api_hangup_hook


I write a custom cpp module for freeswitch that exposes an API:  

SWITCH_ADD_API(commands_api_interface, "my_hangup", "my_hangup",  my_hangup_api , MY_HANGUP_USAGE);  

I want to call this api from dialplan (after bridge hangup) for reading the variable "billmsec".  
I put this into my dialplan:  

<action application="set" data="session_in_hangup_hook=true"/>  
<action application="set" data="api_hangup_hook=my_hangup_api"/>  

After hangup freeswitch call correctly my API but I have not figured out how to get the variable.
