Since both SEA and ASD have SIP trunk to internet.
NA calls: Redmond 10 *0.5 =5 Seattle: 100*0.8=80 Amsterdam: 50* 0.2=10 Berlin: 20 *0=0 Paris: 20*0.5=10 Total: 105 * 100K = 10,500 kbps
Eu calls: Redmond 10 *0.5 =5 Seattle: 100*0.2=20 Amsterdam: 50* 0.8=40 Berlin: 20 Paris: 20*0.5=10 Total: 95 * 100K = 9,500 kbps
Box 1: 9,500 Kbps Box 2: 9,500 Kbps
Transatlantic calls:
Amsterdam: 10
Berlin: 0
Paris: 10
Seattle: 20
Los Angeles: 5
Total number of transatlantic calls: 45
Total bandwidth needed: 5760 Kbps (45 x 128 kbps)
Amsterdam: Amsterdam+ Berlin+ Paris calls to north America: 50 calls x 20% (calls to N.A) x 128 kbps + + (berlin)+ 20 x50 x 128kbps equals 1280 Kbps + 1280 Kbps equals 2560 Kbps
Seattle: 100 calls x 20% (calls to Europe) x 128 kbps equals 2560 Kbps
