We planned network that way no component dependency. We have multiple Internet links and only and only attack we are getting on VOIP RTP server. In last 10 year we never get any single attack on other services except VOIP that's why we 100% isolate VOIP from other services. Believe me we did all home work that's why I'm am asking this last question how to just stop IP frag attack using cisco ACL. 

We have tried ASA too but because of state of connection it didn't won't and put everyone in underwater ASA isn't meant for DDoS. 

Also juniper has option to stop IP Frag attack using offset field.

I'm looking similar option in cisco.
