We have a Digium X100P FXO single-line PCI card installed on our Asterisk test server and it has been working fine. ie. We can initiate and receive PSTN calls and transfer between PSTN and VoIP without any problems.
However, we have had a surprised engineer visit from our telco, British Telecom, yesterday. The engineer said that their automatic fault detection equipment at the exchange has detected a "short" on our PSTN line, the line where the X100P is plugged in. Apart from a 2Mb ADSL line sharing it, there is no other telecommunications equipment attached to that particular PSTN line. After carried out some local tests, the BT engineer confirmed that the detected line fault was caused by the X100P. We have disconnected the X100P from the PSTN line for now in case it would trigger the line fault test again (and we'll be charged for the engineer visit). I suspect that the BT automatic line testing has detected a difference in on-hook line impedance with the X100P instead of a "dead short" as reported by the engineer. Has anyone come across a problem like that with their X100P and UK telcos?
