I am very new to CISCO and would like to learn more. Below is my questions regarding IP telephony.
How can I configure my Cisco to assign a DDI number 6123456X to go to IP. 192.168.239.121 whereas the rest of the DDI number being routed to 192.168.239.234.
Please kindly advise where can I get the correct documentation on the web for me to refer to.
