[cisco-voip] 9971 making phantom / ghost calls - 9.3.x firmwares

[Erick B.]

Is anyone familiar with this issue and knows how to stop the phantom calls
without unplugging the phone?

We had this issue on earlier 9.3 firmware versions and were provided 9.3.2
ES12  which seemed to fix the phantom call issue (or speed dials being used
with no one at the phone) but a few phones still had been doing the ghost
calls on occassion,

We upgraded to 9.3.4-24 firmware a month or so back (before 9.4.1-9 was
 out) and that did not fix this issue with the phantom calls.

The Call Manager CDRs show the 9971 phone is making the calls (MAC Address,
IP address are the phone).

Upgraded to 9.4.1-9 firmware and haven't seen the issue yet (to early to
say) but 9.4.1-9 has very annoying dialing delay/prolonged beep issue that
annoys the user that they can barely make calls on the phones without
problem Seems to be CSCtb02271 from working with TAC on this.


CUCM version 9.1.1.20000-5 (9.1.1a)

Thanks, Erick
