CUCI-Lync cannot register to CUCM 8.5.x

[httung1210]

Hi everybody,

Currently I cannot get my  CUCI-Lync register to my lab CUCM 8.5x, at the softphone mode, the dialpad greyed out and shown message "Calls cannot be placed at this time".

Then, I check on my CUCM, the status for my CSF<userid> is UNKNOWN.

Which could be the possibility to cause this problem?

Please help me out.

Belows are some capture for more details:

Best Regards,

Tung.

Same problem here,

at  times it works at (most) times not.

No way to find out a solution or to find out why it works when it works ...

Ah good past times when Cisco  made   routers and switches only ...
