I added this code into the ser.cfg to execute my script when a mail comes from 10.232.2.225 if (uri =~ "sip:[a-zA-Z]*@10\.232\.2\.225") { exec_dset (<path to the script>); } I have not made any changes except for adding this in the example config file. The script has proper permissions The script is never executed!. What can be the problem? --------------------------------- Do you Yahoo!? Yahoo! Small Business - Try our new resources site!
