UCCE 7.5 - CAD 7.5.1 Agent can not login

Question

Hi everybody,
We're using CAD 7.5.1 for UCCE 7.5.
Currently an agent complait that she can not log in to the CAD due to the error of delay time out. I did a test with her account and here is what I found
- CAD got stucked in the "connect to CTIOS server" step then timeout.
- Her IP Phone is the only one that has this problem. Tested with another IP Phone and they work. Her SEP is well associated with the PG user though.
- Randomly, CAD works. Upon reopening the CAD and trying to reconnect, it stucked again.
I include here the CAD log, hope that helps.

I suppose we have a IP Phone defect since it's the only one that had the problem.
Someone experience the same thing before? Any comment is welcome.
Thanks,

@Geoff:
Thank you for all the good sugesstions, however unfortunately none of them is possible to me
I would try this using the CTIOS client on your test machine, just to  eliminate CAD a little. From the trace, it doesn't appear to matter,  since you are looking at the pure CTIOS trace messages, and they are the  issue - but I like CTIOS for this sort of debugging.
--> We are using CAD and do not have CTIOS client installed. Does the soft actually come with the UCCE installation package? Can you please tell me where I can find it?
@Geoff and Ed
Dissociate and re-associate the device with JTAPI and retest.
--> Good point, I did the same actually but the phone still didn't work.
Nevertheless, I really think we have a network problem (which was observed time to time before)
I will update this thread as soon as I can do some further tests.
Thanks,
Regards,
