[OpenSIPS-Users] Store dialog value and fetch it

[Răzvan Crainea]

Hi, Alexander!

Well, this is pretty weird, since if in the previous route (the one that 
calls the BYE route) you can access the variables you should be able to 
see them here too.
Are you sure you are talking about the same request? Can you print some 
logs in the previous route (the one that calls match_dialog()) with the 
dialog status, method and callid and match them with the logs in the BYE 
route?

Best regards,
