Hello I'm using CUCM 11.5 and using SIP phones. I have my DID's and looks like I have what I need to have setup so that I can connect to my ISTP. but when they dial in, they cannot establish a connection to download their config files.

I wanted to know what else do I need to setup in CUCM? For SIP phones?
