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

[Tim Smith]

Hey mate,

I've seen it on a CME system, only once. It was only a small system with 5 phones.
Only 1 phone was doing it.
In my case there was no bug at the time, and troubleshooting this particular site was difficult, so we decided to try replacing the phone.
It never came back after that.

Sorry, that probably doesn't help too much.
How many phones do you get it across? It sounds widespread.

Cheers,

Tim

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
