Here is the basic network info:
6 remote sites with thin clients, VoIP phones, and some PC's
1 Central office
Database hosted in cloud environment
Thin clients at remote offices need to connect to central office via citrix
PC's at remote offices connect to the shares at Central office
PC's at remote offices connect to the hosted database
Central office connects to the hosted database
Thin clients connected to the central office citrix then route to the hosted database
Need to accomplish the following
Improve VoIP quality between sites
Gaurantee bandwidth and priority to hosted database connectionsduring times of WAN saturation for all locations
Gaurantee citrix connection to central office stays up and as fast as possible
Each remote location has 2 WAN connections, a 6 Mb and 2 Mb connection.
The Central Location has a 50Mbps and 10Mbps connection
They are also using a PET topology between the offices.
Please let me know if you need any further information.
Thank you in advance for your help.

You need to further, and in detail, describe your logical and physical topologies.
QoS can be used to manage bandwidth, which should meet most or all of your service requirements, but for it to really work, it needs to manage all the bandwidth.
For example, if your WAN supports any kind of multipoint, i.e. where more than one other site has a path to another site, you can congest on egress to the destination site, but do you control that congestion point?
You can do a QoS as this :
class-map match-any TrafficoVoipCTRL
match protocol skinny
match access-group name TrafficoVoiceCtrl
match access-group name TrafficoICM
match protocol sip
class-map match-any TrafficoSQL
match protocol sqlserver
match protocol sqlnet
set ip dscp af21
bandwidth percent 5
set ip dscp af31
priority percent 20
