    what ALG's did you disable.


    In case you having cisco ip telephony - i suggest, try to disable.
    set security alg sip disable
    set security alg sccp disable

    I've noticed when upgrading from 10.x to 11. or higher, branch srx devices beginning from srx240 tends to enable sccp without any notifications.
    Probably thats your case as well

    Which voip system are you using?

     

    There are some specific kb articles with configuration examples per vendor that may help.
