[Asterisk-Users] TDM02B on 2 a/b ports of a PBX not working.. . help
I see that no one else has tried to answer your question, so I'll give it a stab. When you connect an FXO port to a PBX, the PBX has to have a way to signal Asterisk that the line has been hung up. The normal (telco) way to do this is CPC (Calling Party Control) signalling, and it is generally either a reversal or removal of battery for a brief period of time. Asterisk calls this "Kewlstart". You need to see if your PBX can be programmed to do this kind of signalling. I have the same problem, except that my PBX will generate a DTMF "D" tone at disconnect. I'm looking for a way to get Asterisk to recognize that in the same way as CPC, and disconnect the call. No luck so far though...

I connected two of these ports to a TDM02B installed on a Slackware 9.1/ Asterisk 1.0.2 and I bought a Cisco ATA186 to connect two analog telephone sets two floors down. Each a/b port is assigned only to one ATA port. The problem is that after the first call, the Digium card fails to disconnect the lines and I keep getting the busy signal. What is more strange is that when I connect the same equipment to two POTS lines of the telco, all run smoothy. Any ideas anyone? How should I setup my line (eg as fxs_ks or something else?)
