Cannot ping external address from a specific vlan

Hello,

I am usig cisco 2911 with dual WAN connection to the internet. I send all voice traffic accross one link and Data traffic to other internet connection. This work very well. 

With PBR and NAT I can send all the traffic of the vlan 20 (voip) on the interface gigabitethernet0/2. Since the vlan 20 I have access to the internet but I can not ping external addresses such as 8.8.8.8.

I send all the traffic of the vlan 5 (data) on the interface gigabitethernet0/1. Since this vlan, i can access to the internet and ping external addresses.

Does the error come from the default route ?

I tried to delete the default route and put 2 but nothing solves the problem.

Do you have any idea of ​​the problem?

In attachment, this is my config router and my schema
