[OpenSIPS-Users] E_DLG_STATE_CHANGED event parameters and values.

[Răzvan Crainea]

Hi, Kirill!

There's no mistake in your code, but in our documentation :). We've 
recently added two more parameters[1] in the dialog event that contain 
the hash_entry and hash_id, but we didn't document the change. I've just 
updated the page[1].

So in order to get the state, you need to add two more AVPs before the 
state, to also fetch the dialog hash entry and id. If you only need the 
state, you can fetch the parameters by their name:

fetch_event_params("ostate=$avp(ostate); nstate=$avp(nstate)");
