I am trying to configure my asterisk to have conferencing capabilities. I dont have any digium hardware (or for that matter, no PSTN line is terminated in my asterisk) in my asterisk server. All calls to PSTN are routed through our main IP telephony server, i.e. Zultys MX250. I have read in a few places that I should be able to configure MeetMe by either using ztdummy or zaptrc. When I was compiling and installing zaptel, I had uncommented ztdummy, but my conferencing is still not working. I am running Fedora Core 3 and Asterisk 1.2.0. When I do lsmod, I dont see usb_uhci in the list. I can’t find zaprtc here: http://www.junghanns.net/asterisk. So, I am not sure where to look for information or how to make it work. Any help would be appreciated.
