Hi, I am a newbie to Asterisk so please excuse me if this is a real stupid question. I configured Asterisk on Turbo Linux and it seem to work fine with 2 phones. Very simple configuration. There was no voicemail and calls were made only from X-Lite IP phones on Windows PCs. I got ambitious and installed Asterisk on Fedora (Core 2) version of Linux. I wanted to be able to set up a VoIP phone system on each of the 100 Windows PCs in my office. Installation was no problem at all. I am able to make calls, but after 2-3 minutes, I get the "503 Service Not available" error on the X-Lite Phone. The message on Asterisk CLI is the "Loop Detected" message 482, "No one to answer the call" or something even though I am calling phones from different PCs. I tried removing the "T" and "t" from the Dial Plan as suggested on some site. No luck. Further plans are to setup voicemail and I have not figured out how to do that yet. I only want all voicemail of the particular extension to be forwarded to the users mailbox.Thats it. What changes are required in voicemail.conf? I do not want to use any database for authentication. I would appreciate any input on this. Many thanks in advance!! Regards Olavo E-mail: olavo@pccegoa.org
