General Firewall Considerations
Listed below are a few models of firewalls which we have prepared specific guides on what to configure, as they have a few specific parameters to modify.
If you are not sure if your firewall is setup properly, do not hesitate to send us an email to email@example.com with your device details and your question.
If using our Cloud PBX service, please ensure that ports 8445-8447 are open for traffic using TCP protocol. This will ensure the user's account configuration will load up properly when the desk phone is plugged in.
