Hackers send the register request to PBX for registry via UDP generally, if it’s
TLS enabled in MyPBX, hacker cannot register extension without the CA, the
registry request will be refused directly.
Refer to Appendix J
to get the detailed steps of how to use TLS in MyPBX.
Note: TLS is disabled in MyPBX by default; we need to enable it in “SIP settings”
page in advance before using it.
2. Firewall configuration
Note: Please back up the configurations on Backup and Restore page before
you go ahead. In the case that you lock the device, you can reset to factory
default and restore the previous configurations. The example rules below work
with MyPBX firmware version 2.15.xx.xx or higher versions.
The basic logic to configure firewall is “Allow all trusted IP addresses
and then enable ‘Drop All’”.
Step1. Enable firewall on firewall page of MyPBX.
