SCCP TCP ports

What ports need to be opened on a firewall to allow a SCCP phone to connect to its Call Manager? I plan to allow only know static public IPs to connect to my Call Manager. I realize that SCCP isn't encrypted but aside from that, are there any know exploits that could take advantage of SCCP?

Thanks,

Diego

Diego,

SCCP uses TCP port 2000. Secure SCCP (SCCPS) uses 2443. See the following link for confirmation.

Hope this helps. If so, please rate the post.
