VoIP WAN Routing Capabilities

Is there a Cisco location that addresses the issue of sizing routers used for voice. We will implement cRTP and transport via DS3 or T1 links. In handling high call volume (500), we hoped to use the 7204/400. I have read this router can handle this, but where in Cisco are the actual test. How many calls, processor needed, compression methods used, voice/data combinations, provision for L2/L3 overhead and safe cushions? Just a few thoughts. Has Cisco any recommendations?
