I have a customer that is running CME 12 and all of his phones located at the office where the CME resides work just fine. We just connected a satellite office to it using a ASA to ASA Site to Site VPN Tunnel. The remote site is working great except none of the phones at that site are allowed to register with CME.

I have both networks defined to CME as Trusted. All of the voice register pools are fine because if I bring the phones over to the main office they register and work just fine.
voice service voip ip address trusted list ipv4 10.100.200.0 255.255.255.0 ipv4 10.10.200.0 255.255.255.0
I am allowing all protocols and ports both ways across the tunnel with the ACLs.
I have no-proxy-arp route-lookup on my NAT statements on both ASA's.

policy-map global_policy class inspection_default
and no inspect sip
