Second PKM 24 goes offline randomly several times a week

[WIBLUESFAN]

I have a receptionist with 2 PKM 24 units. The second one will go offline and the only way I can get it back online is to remove the attached device and then readd it. Seems to be totally random. It'll go months with no problem and then happen twice in the same day. The first PKM never goes offline, only the 2nd one. Tried swapping them, setting up on another phone, changing the connecting cable, same issue. Any ideas?

What model of phone and PKM.  Firmware issue?

Maybe not enough electric juice on that cable, add a properly sized POE injector ?

WIBLUESFAN,

Did you make sure that the external power cord is plugged into the base of the phone?

Thanks,

TE

Unfortunately, that's a common problem with 8528 and 8568 phones. They just go off-line, no rhyme or reason.

You've stumbled upon the quickest way to resolve the issue - remove the device and add it back in programming.

Thanks for all the info. I appreciate it!
