Hey Cisco planet!We have successfully made our Cisco PAM system authenticate and unlock doors for 26-bit standard HID ProxCard II's. Hurrah!However, we have a potential small army of "Simplex" branded cards; they beep when we present them to the read...

Howdy all,We are using a Cisco IAD 2431-16FXS with a 4-port FXO card in the VWIC slot. We are attempting to cross-connect or "nail up" a modem call from one of the FXS ports to a FXO port that is in turn connected to the PSTN. We can dial consistentl...

Karan,That template did the trick! The 36-bit template that I had found indicated that it should have parity, and that the data started on the 9th bit instead of 11. Thank you so much for your direction.Cheers,Randal

Nick,Sorry to be a pest, but is there a platform that is >>> the IAD for this kind of fax/modem PSTN termination? We've considered something like an AS5x00, but our proof of concept is to make it work on an IAD (which is what we have laying around), ...

Nick,We're testing this with the onboard FXS and a VIC2-4FXO if that makes any difference.The -real- question is whether or not this kind of behavior will persist when we replace the 4FXO card with a VWIC-2MFT+PRI. Any input on that one?Randal

Nick,Thank you very much for your informative post. We tried everything listed above, and verified that the calls went from type "tele" to g711ulaw once the DSPs were put back into play, all with the same results -- nothing above ~16kbps.Presuming th...

Nick,Yep, we determined that we can only detect the fax call at the terminating or answering end, so having our Asterisk SIP-proxy won't do any good -- can't listen in on the call, and then switch to the PRI/PSTN service mid-call.That said, we have d...
