I am trying to create a custom script using the GUI of Cisco Unity Express. The script and the application are created successfully with "Dial by Extension anytime" but when i dial the call in number and then try to dial an extension it simply says "You have dialed an invalid phone number." Extensions are three digits in length.Dialing zero is working fine as it does reach the operator's extension. I am fairly new to cisco so I do not know where I am going wrong. The configuration seems to be pretty simple but this is the problem i am facing. Help is appreciated.
