Which TCP/UDP ports do the Codian products use?
Incoming ports • FTP – TCP:21 + TCP ephemeral (i.e. dynamic rather than fixed) ports used for passive mode • HTTP – TCP:80 • HTTPS – TCP:443 • H.323 – TCP:1720 + TCP ephemeral ports for incoming calls • RTSP – TCP:554 • Windows Media Player streaming – TCP:1755 • SNMP – UDP:161 • Outgoing H.323 calls involve TCP connections from TCP ephemeral ports to TCP:1720 + a TCP ephemeral port • Outgoing SIP TCP calls involve connections from TCP ephemeral ports to TCP:5060 • Outgoing SIP TCP calls involve connections from TCP ephemeral ports to TCP:5061 • Outgoing SNMP traps are sent from UDP ephemeral ports to port 162 • Media (including audio, video and FECC messages) is UDP from ephemeral ports to ephemeral ports. • The Codian products allocate ephemeral ports in the range 49152 to 65535. It is possible to change the ports on which Codian products receive and establish connections. For instance, by default Codian products listen for H.323 calls to port 1720 and web browser connections to port
