Hello, To get the username of the caller, I use the following code in my shell scripts: POS1=`expr index "$SIP_HF_FROM" : + 1`; LENGTH=`expr index "$SIP_HF_FROM" @ - $POS1`; USER=`expr substr "$SIP_HF_FROM" $POS1 $LENGTH`; Is there any other way to do that? I need to make a query with the username of the CALLING user... Thanks! Sebastian
