Here is my call flow and issue

Step1 -- Call comes to freeswitch default dialplan

Step2 -- I set some custom channel variables )sip_h_my_var

Step3 -- I fork the call to multiple destinations using bridge application with coma separated list.

Step4 - As one of the destination is my own freeswitch itself, call again comes to same profile with different destination prefix

Step5 - I catch the call in different extension and try to access channel variable sip_h_my_var but get nil value

I tried export application and Bridge application arguments to pass variables but I do not see my variables when i dump variables using Info application. I only see the variables as per the Initial invite (It converts some X- variables to sip_h_X variables)

What else can I try?
