Intermittent Calling problems to international and local no'


Hoping that someone can assist on this, I’m a newbie to Asterisk and started having problems with making outgoing calls to international and local lines, I have had my telephone company here to check my lines and they seem to be working fine.

the calling works and then stops again, after I make one call out, then after that I cannot make any calls again.

Im running Asterisk@Home version 1.3, and need some assistance to troubleshoot if there is a hardware problem on my server or if it is a configuration problem on the server, as far as I know there has not been any changes to the software itself.

please assist

very frustrated…
