[OpenSIPS-Users] Dialog start event over EVI

Mon May 18 15:26:11 CEST 2015

Hey Brett,

For your info, I have tried a similar thing, raising another event out 
of the E_DLG_STATE_CHANGED route however for some reason I could not 
access the avps in there, so not much more info than the original event had.
