DX80 to CUCM via expressway

[PETER MARTLAND]

We have a brand new implementation of CUCM 10.5 latest SU

Presence 10.5

VCS-C and VCS-E 8.5.3

DX80

All registered and working fine except for DX80 messaging but call control non-existent this does not register with the phone device. Anyone had this issue otherwise its off to TAC.

assuming your registering the DX80 to cucm since it won't natively register to VCS-C feature preview of the DX 80 will require X8.6 for mobile and remote access to work.   Been testing in feature preview works well until I tried to join a Rendezvous meeting off conductor from the DX it blows up MRA and the device is useless until reboot.
