[OpenSIPS-Users] Store dialog value and fetch it

[Răzvan Crainea]

Hi, Alexander!

So basically you're saying that after the loose_route() call you can no 
longer access the dialog variable? Are you sure you are calling the BYE 
route only in this place?
You should check if you are really in a dialog context. Inside the BYE 
route, just print the $DLG_status variable. If it is NULL, then 
match_dialog() and loose_route() failed to match a dialog, therefore you 
won't be able to retrieve the value.
Adding the match_dialog() call inside the BYE route only makes sense if 
the dialog was not mached yet. So in your case, it makes sense only if 
you call route(BYE); from a different part of script.

You can't really extract internal dialog values, unless you explicitely 
save them as values, or take them from the request.
