Digital Fax is licensed per channel, regardless the number of users and gateways.
The channel number corresponds to the total amount of concurrent fax calls (incoming and/or outgoing).
Digital Fax can handle up to 90 channels per server.
Digital Fax supports high availability cluster with hot-swap redundancy and load balancing, both for incoming and outgoing faxes. Each server requires a separate license, depending on chosen active-active or active-standby required HA modes. You can add up to 8 nodes to a Digital fax cluster.
Digital Fax runs for 30 days in evaluation mode. During evaluation, Digital Fax allows two concurrent fax transactions (2 channels).
The license can be online-activated from Imagicle Cloud Licensing portal. See here for more details.
