[Freeswitch-dev] bridge application : how to retrieve data field

Hi, I develop my own endpoint. I have a question regarding the xml dialplan rule like ( I take openzap for the example) : <action application="bridge" data="openzap/1/1"/> I understand that the first field of data is the mod name. The remaining "1/1" is useful for openzap to select the right channel, Where is 1/1 passed in Freeswitch ? In a callback routine of the mod ? or elsewhere ? Regards, Ludovic
