dial asterisk from sql

We need some custom scripting done for our Elastix server. currently, our agents connect to a SQL database with telenet and use key combinations to call a customer. DR Dials the number in the residence field DW Dials the number in the employment field DN Is used to dial and other number. (Example) DN96013555211 would dial the office DX*70 Plus the extension transfers calls This sends a dial command via serial port to an external analog dialer. We need Elastix to accept theses commands and do the dialing. Thank You.
