I am running * in a development environment, adding functionality as I go. The * box has a X100P card in it which ztcfg enabled as channel 1 with fxsks signalling (fxsks=1). Everything worked fine and I was able to make inbound and outbound calls to/from the PSTN, the only issue being that some exchanges wouldn't handle the dtmf signalling, but I put that down to a peculiarity with some AU exchanges and I was able to overcome it by using pulsedial signalling. Anyway, I thought I would next slip in a PCI USB card so that I could use the USB analogue converter thingy, so I stop the * box and drop in the card and reboot. At this stage I hadn't adjusted /etc/zaptel.conf to cater for the extra channel, but when I rebooted the box ztcfg suddenly complained that it couldn't find the existing X100P card; the error message was something like: ZT_CHANCONFIG cannot config channel 1 - no such device not exactly that but you should get the idea. At this stage I went back to square one and ripped out the USB card, but to no effect, and this made me think that the X100P card had gone belly up, but why that would happen between reboots is a mystery. I then decided to put the USB card back in, comment out the reference to the fxsks signalling for the X100P on channel 1, and put in the signalling line for the USB device on channel 2 (fxoks=2). No good, ztcfg now complains that: ZT_CHANCONFIG cannot config channel 2 - no such device Now that makes me think that there might be nothing wrong with the X100P card but that the problem is more software related. I have tried recompiling the zaptel source and re-installing but to no avail. The version of zaptel is CVS which I downloaded on 3 Dec. Now, when I run ztcfg I get a seg fault. The only change that has been made to this box recently is to run up2date to update the rpm packages (Fedora Core 2) but there was nothing updated that could have impacted in the re-compile of zaptel. BTW, running kudzu on this box to discover hardware found the X100P card (which it describes as "Individual Computers - Jens Schoenfeld|Intel 537") and it find the USB thingy which it describes as many things (lsusb describes it as: Bus 001 Device 002: ID 06e6:831c Tiger Jet Network, Inc. Bus 001 Device 001: ID 0000:0000). Has anyone any advise on this matter. -- Howard.
