It all depends on what Codec you going to use and transcoding
here is the cisco b/w Calculator for the VoIP phone depends on Codec

The phone types really arent that relevant. Check the regions settings and verify what codec they use so say 100 phones using g711 would consume about 100*(64+20%overhead) so about 8mbps. Video is around 2.5mbps on an sx10 using 720p
