Digium TDM21B - 1 FXO 2 FXS

Please Note: The Digium TDM21B has been discontinued. For an alternative, we highly recommend the Digium A4 Series.
The TDM21B 1 incoming line (fxo) and 2 phone extension (fxs) serves as an interface with analogue telephones or analogue lines for integrating into Asterisk PBX.
Used in conjunction with Asterisk a user can create a SOHO (Small Office Home Office) telephony environment which includes all the sophisticated features of a high end PBX platform.
The TDM21B 1 incoming line (fxo) and 2 phone extension (fxs) takes the place of an expensive channel bank and brings the system price point to the lowest in the industry. To scale this solution simply add additional modules or TDM cards as required. Until now, this low cost and revolutionary solution had yet to be filled in the telephony space.
This product has been discontinued.
