[OpenSIPS-Users] opensips 1.6.4-2 and dlg_end_dlg

[Bogdan-Andrei Iancu]

Hi,

You are doing something wrong there - based on the script, it seems you 
do "dlg_end_dlg", which triggers sending BYE -> local route -> you do an 
exec there to do again dlg_end_dlg. So you try to do nested FIFO 
commands which does not work - FIFO engine will not read a new command 
until the current is not finished.
