I configure a UC500 with zone-based firewall. After that, the fxs ports cannot be registered as sccp. I run the "show sccp all" and the cause code for the error is "TCP_CONN_ERROR". Any help? I am attaching the configuration.

Can you add "match protocol sccp" to the following class map:

class-map type inspect match-any cmap-internet-traffic

Let me know,
