Allowed ports in ACLs for Wireless IP-Phones

I need to Apply ACL on one SSID which is used to allow the communication between just IP phones and for sure CallManger.

So I need to know which ports should I allow in ACLs:

I tried to allow the following ports:

UDP>> DHCP

udp port 69 TFTP

tcp port 2000 SCCP

udp range 16384 32767 FOR RTP Streaming

shall I enable any thing else????

These ports are fine.

CallManager discovery can occur several ways, one of them is DNS. If you use DNS discovery, you may want to add UDP 53. If CUCM information is fed from TFTP server files, then you are good with the ports mentioned in your list.
