Wondering if anyone has seen this particular problem before i issue this to TAC:
CPE: Cisco 7970 IP handset
Appliance: Cisco UC500 16 User
CPE Loads: 8-5-3S (recently updated to try and combat the problem
After coming in of a morning, 3-5 handsets out of the 8 connected become unresponsive, their screens are still functional, however when calling the ext it goes to VM immediatly, and when you pick up the phone it gets no dial-tone (No Auto Line selection).
Measures used to Resolve Issue:
- Updated the phones to the latest phone loads (As above)
- Reset the phone every morning to bring it back to life
The phone is showing up as registered, i can even ping it, it is almost like as if it hasn't woken up from its slumberous sleep but still has some response capabilities.
Short of now looking to update the IOS version, i cant seem to find anyone else who is having or had this problem, so i have no reference point to work of to try and resolve this issue, i would like to avoid getting TAC invloved unless i need to RMA the units that are having this issue.
Any advise or information regarding this matter would be greatly appreciated.
Thanks in Advance.
