There are a few users in my company that has caller id issue when calling external numbers. Everyone in the company has their DID as their phone number mask in their line and no calling number transformation happens anywhere. When those few users in question call external numbers, it shows 'unknown' as their caller id. I had asked the user to login to another phone (we use phone auto registration and extension mobility) and place the call and still shows 'unknown' as caller id. We have CUCM ver 11.x and CUBE for PSTN. Can someone help me solve this issue?
Thanks, Khanal
