Hello List, Does anyone know of a device that works with the TDM400P FXO/FXS Modules to provide line backup for power failure?
I have an idea for such a device but do not have enough vision to do the soldering of the parts. My ideal device would be able to sense when asterisk has brought the FXS port up and then switch a relay over so that the phone was connected to the FXS interface. Then if the FXS or asterisk failed for any reason and the line was dead the relay would drop into default state connecting the phone to the external PSTN trunk. Now for the reason I need such a device. My Girlfriend has CP and cannot manually manipulate phone lines to switch a cable if the asterisk box were to go down. Also once she is in bed, she can not get up by herself to get to another phone. I know there the Sipura 3000 does auto line fail over but from discussions with a couple people who have them. The sound quality is bad and the line fail over reverses the polarity and makes the Nortel phones unhappy. If someone has a suggestion for a place to buy such a device or wants to build a prototype for me to test I would appreciate it.
