If I have a new checkpoint firewall in a remote site with only 1 rule (internal network) to ANY, Allow. (only the firewall blade is enabled, all other blades are inactive). This new connection is exclusively for VoIP connectivity to a cloud phone service. Is there any recommend or best practice rules/settings/or global properties to maximize reliability on this connection? I need to ensure that any packets destined to the 8x8 phone cloud does not get slowed or interrogated by any mechanism that might disrupt audio quality/reliability.
We're getting some complaints in the current configuration on call quality and reliability.
