For H.323 endpoint firewall traversal for calling outside the Cloud, refer to Firewall configuration for calling between the StarLeaf Cloud and H.323 endpoints .

For StarLeaf endpoints to be able to access the StarLeaf Cloud service, certain ports on the public IP addresses of StarLeaf Cloud must be reachable for outbound connections through your firewall.

H.323 endpoints registered to the StarLeaf Cloud must use the H.460 protocol to traverse its firewall and connect to the StarLeaf Cloud, if the endpoint is on a private IP network (behind NAT). Some endpoints use H.460 automatically, while others only do if they have been configured to do so.
