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 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.
All ports used are documented in the following url:
