ISDN BRI Cards

Basic Rate ISDN (BRI) is the equivalent of 2 digital telephone lines / channels. As a business you can purchase multiple banks of ISDN channels, going up to a maximum of 8 channels. A bank of numbers (called MSNs or DDIs) will allow multiple numbers to be allocated to a much smaller number of incoming lines. Line Caller ID is also extremely useful to determine incoming callers' numbers.

Our ISDN card solutions have been tested with Asterisk. All cards here are active and are meant for production type environments.
