How to configure QoS with Adtran netvanta and Avaya IP Office switch

I have two sites with a VPN tunnel in place but I have no idea how to configure QoS on the Adtran Netvanta 3120 Routers at both sites.  I have included a config file from one site, the other site is identical. One site has the PRI and all VoIP is carried across the VPN tunnel to the other site.  Both sites are using Avaya IP office switches and I have absolutely no idea how to setup this QoS.  Both sites are 1.5Mbps up and down and normally there is no issue but at high peak usage we get some loss and jitter.  Both routers have latest Enhanced firmware, upgraded today but I need some input on setting QoS on them.  If anyone has any info...

Your help is always appreciated.

not sure about the Avaya side, but you'll want to mark QoS from the phones as well as on the switches not just the routers. The routers will look at the markings and go from there so if the Avaya is using DSCP values then you can setup policies with those. If it's using tosbit you set accordingly the basic setup on the adtran boxes would look like

qos map mapName 20                                                                
  match ip rtp 10000 10048                                                      
  match dscp 46                                                                
  match precedence 5                                                            
  priority percent 66                                                          
qos map mapName 21                                                                
  match precedence 3  
  match dscp 26                                                          
  priority percent 4                                                            
  set dscp 26    

so you setup a qos map and give it a name and a value, the value is basically irrelevant except the lowered number maps will be checked first. the match commands will check traffic and if it matches it'll use that priority set. so for example in the snippet above, if the packet is makred with a DSCP value of 46 it goes out before a packet marked with 26. packets marked w/ IP precedence of 5 go out before packets with precedence 3, anything in the RTP port range set goes out that first qos map

you can set priorities as either a strict bandwidth in kbps (1024 for example to set 1 mbps) or as a percentage of the link bandwidth.

then on your WAN interfaces you have somemthing like
                                                                     
interface ppp 1                                                                
  description ppp 1                                                            
  ip address 10.10.10.2  255.255.255.0                                    
  media-gateway ip primary                                                      
  qos-policy out mapName                                                          
  no shutdown                                                                  
  cross-connect 1 t1 0/1 1 ppp 1  

where you apply that QoS policy to that interface, use the media-gateway ip primary on any interface that has voice traversing it, setup your IP's and any access policies, then the cross connects. pretty straightforward.

It just depends on what kind of QOS marking you're using on the IP office box and on the IP phones themselves.

I have added the above lines using cli and they have had no effect.  I should have mentioned that the avaya ip office switches are connected to the routers and the phones are actually digital from the ip office switches instead of IP phones.   Not sure if the QoS works with digital phones, thanks for your input.
