WG.  This activity is now approaching its  completion.  <color><param>0000,0000,0000</param>

The Call Bearer Control protocol specifies a ‘vertical’ interface
between a Call Control entity and a Bearer Control entity.  This
enables the offering of a full set of telephony (BICC) services,
independent of the underlying transport network.

The Call Bearer Control protocol has been based on the SG16
protocol H.248.  It uses the H.248 format, H.248 descriptors, H.248
 encoding, H.248 defined packages, etcetera.  Seven new H.248
packages have been defined.
