Step 5. Add a Firewall Rule for VoIP trunk registration
Note: If there is no VoIP trunk, this rule is not required. And if the RTP IP
address of VoIP trunk and Registration IP address of the VoIP trunk are different,
we need to create a rule to accept the RTP IP address too.
Add a rule to accept the IP address of the VoIP trunk to access MyPBX server. For
example: If the IP address of the VoIP trunk is 110.5.14.6, Protocol is UDP and
Port is 5060, the configuration could be as below:
Name: VoIPTrunk
Protocol: UDP
Port: 5060: 5060
IP: 110.5.14.6/255.255.255.255
Action: Accept
