Hi,
    As it is very clear that any End Point may operate in specified set of capabilities depending on the policies or bit rate or whatever. When the call is in proceed on a particular codec,  what are the factors which decide on changing to a new codec ?
Is user allowed to change codec when the call is in proceed ?
( Assuming that the other end point indicated MaxPendingReplacementFor capability )
 
  Can anyone help me in this regard ?
 
thanks
Martin D.
