Hey Carsten, going forward on IMS, is your plan to standardise on K dialog or S dialog for SR3? Have been going through the code of the scscf which relies on S dialog. K dialog has alot more functionality and state management? what are your thoughts? Having completed a PoC Ro interface (which you wil notice from the code is based on K dialog) I now need to incorporate into existing S-CSCF, which will have to be changed from using S dialog to K dialog. Cheers Jason
