Tracking Down Issue of Caller Name showing is not matching on Mitel Server

[HungryHippo]

Good Sirs,

I am not sure where to start on tracking this odd issue. I have been told by two users that sometimes when they call out to external number the name showing is different from what we have setup on the Server. Both have a DID of their own and its currently setup to show as the outgoing number. Im checking the smdr logs but all I can see are numbers? Is this an issue with our carrier or the other/called party's carrier? I'm not sure how this works with mitel with the caller name.

The name is normally handled at the carrier level and not the PBX.  Call your carrier and see what name they send based on the DID.  I've also chased this for the dumber reason of the person they called has a named saved in their cell phone which will ultimately show over any caller ID.
