I am running into a strange problem on my UC520 with a PRI. If somebody call ours main number the call goes to a blast group which rings a handful of phones. All phones display the caller id number but not the name. Once somebody in the blast group picks up the phone and the call is connected the calling party name is displayed correctly on the phone along with the number.
Now if someone's DID is called the name is never displayed at any point. I ran a q931 debug and I am able to see calling party name in every call that is coming through. I have also verified that the isdn supp-service name calling command is enabled for the D channel.
