I don't think this feature is available on the CUCM Linux version since it's an appliance device.
You can check the CUCM firewalltable by issuing the CLI command:
utils firewall ipv4 enable
You can also check for the list of open ports with the CLI command:
show open ports all

Hi Friend ,
The following command can be executed in CUCM CLI to know the " STATUS OF THE PORT " in our CUCM Server which is of importance.
# show open ports regexp <PORT NUMBER>
* PORT NUMBER = Replace it with the PORT NUMBER of your interest.
Example : I had a CUCM DB Replication issue.So as part of troubleshooting, I need to check whether the PORT 8500 ( Port for DB Replication ) is OPENED / CLOSED . So I ran the following command and got the appropriate output.
**************************************************************************
admin:show open ports regexp 8500
Executing.. please wait.
clm 22712 root 6u IPv4 662221 0t0 UDP *:8500
clm 22712 root 7u IPv4 662222 0t0 TCP *:8500 (LISTEN)
clm 22712 root 10u IPv4 183481931 0t0 TCP 10.106.102.70:8500->10.106.102.71:40657 (ESTABLISHED)
clm 22712 root 11u IPv4 183485707 0t0 TCP 10.106.102.70:8500->10.106.102.72:47472 (ESTABLISHED)
***************************************************************************
Hope this might help. Thank you.

additionally you can do a packet capture on your cucm, and see if its sending traffic back, from port 5060 (in your case)
