UK(b) - Although UKb already have facilities to negotiate reverse charge, the billing programs ignores this information. Therefore UKb effectivly do not support reverse charge. There is an enhacement at LOG II to pass reverse charge information to the SUP when a call setup is requested. I dont think this is required for reverse charge billing, but we need to check this.

&UKa& = yUKa support

Already supported - no change

&UKb& = yUKb support

X.25: Supported
