Who Me Too'd this topic

Has anyone here dealt with Googles hangout app for mobile devices going through the firewall. The customer wants to allow hangout chat but not file-transfer or video calling. The apps sees it as google-talk and under it is gtalk-voice, google-talk-base and gtalk-file-transfer. If we set up the policy for app filtering would the gtalk-file-transfer be masked by ssl or would it still be seen?

I am thinking it would be masked so an ssl decrypt policy would need to be employed. However when I enable the ssl decrypt, the device then can not sign into google hangouts.

Any thoughts or help would be appreciated.
