thanks for your recommendation. i have 2servers one trixbox and one elastix1.6.
in this situation i have a sangoma a200 card therefor i have to use trixbox. if you can help me for installing sangoma a200 on elastix 1.6 i promise switch to elastix1.6.
i have switched to elastix1.6 and install sangoma a200 correctly
for installing sangoma a200 on elastix 1.6:
1- first login with root and run "lspci" . you should see sangoma a200 in the output
2- run "wancfg_dahdi" and in the wizard accept default value . notice that when ask "would you like wanroute to automatically start on startup?" you should response with "yes".
3- finally save changes with select "restart wanpipe and asterisk"
now in system's tab and in the hardware detection you should see sangoma a200 card with in use port.
