EPM and Aastra 6757i L1, L2 configuration

Hello,

I have a 6757i responsible for answering for multiple companies. Using CID name prefix answering using the correct company name is not a problem. However, making outbound calls the receptionist would like to select which outbound number to push.

I set up another extension with a different Outbound CID to be used as a line key, but I’m not able to map this in EPM. Can anyone tell me if this is the process I should be using and perhaps have an example using L1 or L2 buttons?

Thank you,
