IP telephony port to be used

Good morning,

I need to secure an IP telephony environment with FW rules and ACL.

Do you have a list of the ports required?

ANy document link and CCO doc?

Thanks

Matteo

Take a look at the following documents:

TCP and UDP Ports Used by Cisco CallManager 3.3

http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a00801a62b9.shtml

TCP and UDP Ports Used by Cisco Unity Version 4.0

http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_white_paper09186a00802077c0.shtml

Hope this helps.

Brandon
