Don't do that. This is your customer, you are going to be the one
taking the heat  when this customer is screaming angrily at you about
poor voice quality. Over VPNs, you're going to have an awful time even
making an attempt at troubleshooting.

I'm a ccie =) do i count?

There needs to be QoS for voice for it to be supported. if your
customer does something like switch all of these acquired company
sites to the same ISP as your main saite, or ISPs that offer guranteed
QoS between each other. An MPLS VPN or dedicated site-to site circuits
would be ideal for this type of thing so that there's no encryption
taking place on the voice.
