Does DM Fax Server for FoIP use fewer ports/channels than DM Fax Server for PSTN-based faxing?
No. Because DM Fax Server in a FoIP configuration sends and receives faxes is in real-time, the same number of channels is still needed. A fax session will remain open until the transmission is completed. Furthermore, because the faxing is in real-time, the gateways/routers don’t cache any of the data, so again the same number of ports/channels is required.
