Hi,
I just set up a car dealer with 6 different zones,3 different MOH, Tenanting for MOH and Night 1 and Night 2, LBN 911 & 988 for paging using LS trunks on each Cx controller. 6 different page zones with external ringers at each zone.
All IP users on 1 controller using MPLs to connect them together.
6 cx controllers,2 MBG using SIP,1 MAS UCC v2 using TW, twining. When I was done with this project learned a lot.
If you are still having issues let me know.
Scott
