I did installations for Star2Billing version 1.9, I copied the a2billing.conf to the /etc/, also I enabled the manager.conf with port 5038. I copied a2billing.php and the lib to the agi-bin directory and I ran chmod +x for a2billing.php to make sure it is executable. And my php packages are: [root at Call-Bilal asterisk]# rpm -qa | grep php php-pgsql-5.2.9-2.fc10.i386 php-pear-1.7.2-2.fc10.noarch php-common-5.2.9-2.fc10.i386 php-pdo-5.2.9-2.fc10.i386 php-mbstring-5.2.9-2.fc10.i386 php-cli-5.2.9-2.fc10.i386 php-5.2.9-2.fc10.i386 php-mysql-5.2.9-2.fc10.i386 php-imap-5.2.9-2.fc10.i386 php-gd-5.2.9-2.fc10.i386 Note: I am able to place a normal call frome extension to extension but using a2billing, no success. Any help? Regards Bilal
