I'm unpicking some of the dustier corners of our CUCM setup and hit something I can't work out.
We've got some MGCP Euro ISDN-30 trunks. With Euro ISDN, the leading zero of the presentation number is not sent by the network. Yet when the presentation number is shown on the handset, the leading zero is there. I can't see anything in my configuration which adds it in, so it CUCM automagically adding in the leading zero?
