This kit allows you to upgrade your Talkswitch 48-CA to a Talkswitch 48-CVA, the 280VS to a 284VS, or, a 480VS to a 484VS with VOIP capability. This kit CANNOT be used with a Talkswitch 48-NLS as they are different internally, we have a separate item for that.
Talkswitch is an expandable system. You can hook up to 4 of these together (networked)! Hooking multiple units together provides an equal number of additional incoming lines, local extension, VOIP trunks, and remote extensions. Therefore, 4 484VS as an example hooked together provides 16 incoming lines, 16 VOIP trunk lines, 32 local extensions, and 32 remote extensions.
Talkswitch VOIP products include a SIP server and registrar, no need for external SIP software! The SIP software is fully functional, you can assign 3 digit extension to remote VOIP extensions. This means the Talkwitch is using TCP/IP unlike the older 48 models. By using TCP/IP, not only does this allow the Talkswitch to do VOIP, but now other possibilities emerge for the Talkswitch.
