I have a Vonage acct that uses the Cisco ATA186. Currently, I have the ATA186 plugged into a SPA3000 to act as the FXO port. I installed a X100P card with the idea of replacing the SPA3000. Now, when I plug in the ATA186 into the X100P card and make a call into the system (from cell phone) and hangup when the IVR is playing, Asterisk is not detecting a hangup and keeps looping the IVR. If I plug in my POTS line into the X100P, everything works correctly. I found a few posts dating back to '03 regarding this specific issue, but I don't see that it was ever resolved. At that time, it appeared to be a issue with the ATA186. Does anyone else have an ATA186 plugged into a X100P card? Do I need to add/change any specific parameters in the zapata.conf file? Thanks, Doug
