service-policy, class and policy map and ACL impact on IPT?

Other location has a leased line of 2mb. to main office where PBX is. Remote location has 4 vlans. Each entity has 2 vlans namely for voice and data. the LL is divided by 2 (each entity half of capacity) and each part again divided via service-policy, class and policy maps a diffrent priority so voice gets priority and a fixed bandwidht. When we tested in beginnen there were no problems with voice but once up and running :-( (once data also got active) Now we tried alread a lot (bypassing fw and so on) but jitter remans for IPT. Only thing I stil can think about as cause is: all those maps and policy takes each packet to go through a long proces before being send so causes jitter. Anybody and advice or experience?

Hi

Can you post your configs?

There's lots of things it could be, but it definately looks like the LLQ isn't working for some reason... Do you have CAC configured adequately in some way?

I've seen on one version of IOS LLQ simply didn't work, upgrading fixed it... but it would be worth seeing your config first to confirm it.

What routers are you running etc?

Hi Aaron,

In attach config. Routers are 2000 series.

First all traffic was going through FW (tunnel) but we thought that could be the bottlenect so bypassed it. ERicsson is attached to Catalyst5500
