[OpenSIPS-Users] Store dialog value and fetch it

[Alexander Mustafin]

Hello!

I’ve tried many variants, but unsuccessfully.

After BYE message, dialog change state to [5] and fetch_dlg_val doesn’t export any stored values.

Are the other ways to save dialog-related values after BYE message?

Best regards,
Alexander Mustafin

>> 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.
