I'm having four branches in multi-site deployement, all registered to HQ running cucm 8.6. I'm about to install another branch which will also register to HQ. The DN's for this branch begin with 0, e.g 0000 as a main DN then 0001,0002-0299. In my country we dial 0 for seconday dial tone. now when trying to dial internaly you get seconday tone after pressing the 0. it overlaps with my local parttens. How do I overcome this issue?
