Hello, Our phone operator installed a ISDN Network Terminator type NT1-2ab 4B3T. This device is able to handle 2 analog (RJ11) and 2 digital (RJ45 ISDN) devices. On this device we have our main phone number and a MSN number. But how do I now link this to the network. We have IP phones from LinkSys type SPA962. The MSN is plugged into the analog port and is used for our fax. This works fine. Do I need some interface device between this terminator and the VOIP network? If yes, then please specify what type of device. We probably will use a LinkSys device because our phones are from LinkSys. Will it be possible to handle multiple incoming calls in this setup? Thanks.
