Hi! Has anyone of you used a database to make routing? For example: If the caller marks 001 -> Rewritehost("xxx.xxx.xxx.111"); If the caller marks 0049 -> Rewritehost("xxx.xxx.xxx.222"); The two host names are in my postgres database... Once I used a command like this to stop calls of users that don't have credit: if (!exec_msg(' POS1=`expr index "$SIP_HF_FROM" sip: + 4`; LENGTH=`expr index "$SIP_HF_FROM" @ - $POS1`; USER=`expr substr "$SIP_HF_FROM" $POS1 $LENGTH`; QUERY="select credit from subscriber where username=$USER AND credit > 0"; RESULT=`psql -U postgres AAA -t -c "$QUERY"`; if [ -z "$RESULT" ] ; then exit 1; fi ;' )) { sl_send_reply("403", "Sorry, not enough credit to make this call."); break; }; ... but I have problems to get the result of a psql query... is there any way to do it?? Thanks!! Sebastian
