We have a connectivity problem with our CUE, we installed a new ISM Module in our 2911 router, and basically the CUE is reachable from the router, but it's unpingable anywhere outside the router, we followed the instructions advised by Cisco exactly, but till this moment we are unable to reach it, noting that we have ZBF configured and we are able to ping everything in VLAN 14 which is the voice vlan except the CUE, below is a snap of the config and couple of show commands we have typed on the router :
IIAB-Irb-Husun-R1#service-module isM 0/0 status Service Module is Cisco ISM0/0 Service Module supports session via TTY line 131 Service Module is in Steady state Service Module heartbeat-reset is enabled Getting status from the Service Module, please wait..

I'm trying to reach the CUE from my PC on the LAN, i'm connected to the switch directly which is connected to the voice gateway via a trunk connection and the setup is basically a Router on stick, and i can see the IP Phones in VLAN 14 from my PC where i'm in VLAN 12, so i guess the routing should be ok, from the voice gateway i can login to the CUE and configure what i want, but inside the CUE, i can only ping the gateway and nothing else, even though CUE supposed to be a member in VLAN 14, but i cannot ping it.
I was thinking that ZBF maybe the cause, but since I can reache the IP Phones and ping it without any issues, CUE should be the same.
