I have a setup of Asterisk 1.2.28 and Digium AEX808B (8 FXOs), I connected the PSTN lines to the Digium card, everything is working fine but the issue is that when I make calls through the PSTN lines, some of calls get out successfully and the other give me a different dummy long ring back tone for about 12 seconds until it hangs up. I have taken the server with the card to another location in the same city, the same PSTN Company, but different exchange, everything worked fine, as well I tested it with a Prima Cell, and worked fine, I want to find the issue to try to sort it out. Any help will be highly appreciated.
