Maximum (3) Expansion Licenses per system (Total 16 ports).
The maximum quantity of VoIP ports in a DSX-40 is 8. The maximum quantity of VoIP ports in a DSX-80/160 is 16.
A DSX license can only be used at the site associated with the specific 13-character code that is provided on the purchase order.
In order to purchase a license, you must first upgrade the specific DSX system with Version 3 software, and if expanding VoIP capabilities, the VoIP Daughter Board must be installed.
Placing orders for DSX Licenses requires that you provide us with a unique 13-character code, which is obtained from the working Version 3 DSX system. This code is unique to each DSX site and can easily be retrieved through the DSX Admin Program.
Entering the new license code in the DSX system will enable the purchased licenses. Purchases of DSX Licenses are final.
