Upgrade a 48-CA to a 48-CVA with 8 total VOIP paths, 240VS or 244VS to a 248VS, 280VS or 284VS to a 288VS, 480VS or 484VS to a 488VS, 840VS or 844VS to a 848VS. This upgrade kit is not for the older Talkswitch 48-NLS or LS, there is no upgrade path for them. This adds VOIP capability to the listed models, a total of 8 paths that can be used for VOIP phone lines, to communicate between multiple Talkswitch systems via VOIP, or, to allow use of remote IP phones as local extensions. The kit includes an instruction manual (very short!), a top board, and a few screws. It takes only a few minutes to do the work. No configuration is lost, you just have to configure VOIP services. |
