I'm running CUCM 7.1.3 and have some 7921 running firmware 1.3.4.
When I try to dial out of corporate directory, it translates the +41614675XXX number to 0004. For internal dialing, there are 4 digits (5XXX) used.
All DN's and phones has the same CSS and are in the same partition. This happens just on the 7921, on all other phones dialing from corporate directory works fine.
Has someone made the same experience? Might this be a bug?
