[cisco-voip] 8865s and MRA CUCM registration failover issue

[Erick Bergquist]

Has anyone seen where 8865 model phones don't register over MRA  in
the UCM group if the some servers are not reachable?

8865s with 12.5.1 SR3 firmware
12.5.1 SU1 CUCM

2 expressway pairs

UCM group order (same as service group),

CCM1
CCM2
CCM3

When CCM1 and CCM2 are unreachable the MRA 8865 phone just spins at registering.
Once CCM1 or CCM2 become reachable, the phone comes backs up.

DX 70's and DX 80's register fine when CCM3 is only available over MRA.


Thanks,
Erick
