You need to do the following :

- First enabled dns lookup

(MASTER-CONTROLLER) (config) #ip domain lookup

- Add a DNS server

(MASTER-CONTROLLER) (config) #ip name-server 192.168.1.103

 

"This will require a reboot to take effect"

 

- Then create a netdestination for whatsapp

(MASTER-CONTROLLER) (config) #netdestination WHATSAPP
(MASTER-CONTROLLER) (config-dest) #name *.whatsapp.com
(MASTER-CONTROLLER) (config-dest) #name *.whatsapp.net

 

- Create an ACL to block all traffic to that netdestination

(MASTER-CONTROLLER) (config) #ip access-list session WHATSAPP-ACL

(MASTER-CONTROLLER) (config-sess-WHATSAPP-ACL)#user alias WHATSAPP any deny

- Then apply this to your user-role

(MASTER-CONTROLLER) (config) #user-role guest

(MASTER-CONTROLLER) (config-role) #access-list session WHATSAPP-ACL position 1

It is very difficult to block without deep packet inspection. They have designed it to get through most networks because of places like China.
