* File: dvcsplay.cpp
* Content: Implementation of CDVCSPlayer class
* History:
* Date By Reason
* ============
* 07/22/99 rodtoll created
* 10/05/99 rodtoll Added comments, dpf's.
* 10/29/99 rodtoll Bug #113726 - Integrate Voxware Codecs, updating to use new
* pluggable codec architecture.
* 01/14/2000 rodtoll Updated to support multiple targets
* 03/28/2000 rodtoll Updated to use new player class as base
* rodtoll Moved a bunch of logic out of server into this class
* 11/16/2000 rodtoll Bug #40587 - DPVOICE: Mixing server needs to use multi-processors
* 09/05/2001 simonpow Bug #463972. Added constuct/destruct methods to enable
* allocations and de-allocations via CFixedPool objects
* 02/28/2002 rodtoll WINBUG #549959 - SECURITY: DPVOICE: Voice server trusts client's target list
* - When server controlled targetting is enabled, use server's copy of client
* target list instead of list specified in incoming packet.
* - Fixed crashed caused by updated bilink code.
