Note: Static public IP range needs to be configured here, if it’s dynamic IP address that
doesn’t belong to a range, there is no need to configure it, but the “Drop All” in the next
step should not be ticked. The IP blacklist rules will help to protect MyPBX. We
recommend getting public static IP for security purpose.
Step4. Add common rules to accept the static public IP range of
VoIP provider.
The ports used to contact the SIP provider is 5060 and 10000-12000 by default, if you
have changed this port range, you can input it here by yourself.
For example, the IP address is 110.111.132.6, the configurations should be two parts, one
is for 5060, and the second is for RTP port: 10000-12000.
Allow registry port: 5060.
