[OpenSIPS-Users] Provisional response handling in case of forking

[Bogdan-Andrei Iancu]

Hi Agalya,

First, take care that you can set and trigger only one reply route per 
transaction!

Now, looking at your logic inthe script, it does not reflect your 
statement : keep and log the first 180, drop the others <- is this correct ?
