[cisco-voip] CUCM 12.5 CCMAdmin login error

Wed Apr 3 08:53:45 EDT 2019

There were a bunch of phones(79xx) deployed with bad spring in the hookswitch:
CSCto78441

Symptom:
7962 phones are going off hook and then on hook 400 milliseconds later, which prevents the user from answering the call properly. This behavior can be seen in the SDI traces:

11:33:42.540 |StationInit: (0000030) OffHook.|1,100,49,1.584290

and then back on hook roughly 400 milliseconds later:

11:33:42.981 |StationInit: (0000030) OnHook.|1,100,49,1.584297

Conditions:
This can occur on 7942 or 7962, and is more likely to occur when the phone is sitting at a steep angle and especially with a sidecar attached.

Workaround:
1. Invert the wall mount tab to be in wall mount mode.

2.  Reduce the angle at which the phone is sitting by two notches.  This may not be possible if a sidecar is mounted.

3.  Do not use a handset, use only a headset.

4.  Open a case with Cisco Customer Service or Cisco Technical support to have the affected handsets replaced.

If you find it sticking, lift handset and depress and release hook switch repeatedly ten or twenty times.”
