Hello everybody,
I have the following situation:
- A WAN VoIP network, with centralized call processing model (central site and few branches)
- Cisco IP Phones 7945-G and 7965-G running SCCP
- Cisco Unified Communications Manager 8.6(2a)
- SCCP firmware Release 9.2(3) for the above mentioned hardware models
The problem that occurs randomly is that either when the firmware was SCCP firmware Release 9.2(1), or it was upgraded to SCCP firmware Release 9.2(3), approximately 5 Cisco IP Phones, the screen goes blank, the phone being still operational (but difficult to operate in such circumstances), and the problem persists until it is disconnected from PoE, and re-connected.
Please if possible, any solution to this problem is much appreciated.
Thank you in advance.
Radu
