Re: [SR-Users] BLFs are not working

Hi there... Trying to get the BLFs working... Not much luck Registration works and device to device calls work but the BLFs dont.... Does anyone have a basic config where the BLFs work and calls work that I can try? If not, can someone point me in the right direction? I get LOTS of these types of NOTIFYs but never one with a body...
