Root Cause!!
We engineer would like to think everything happened for a reason, right? But sometimes we see some unusual phone behavior I can't find any explanation for my customer.
*one extension was used as a shared line but was only ringing on one phone only!!!
Phone reset resolve that issue.Reason: was registered to the different subscriber.
??
*Sometimes No dial tone.Normally phone reset to resolve this issue.But Cisco was kind enough to give us an engineer special firmware version for the phone.
>Not sure that resolve the issue.But still having the same phone stuck with an older version.
?Why now? same firmware we have been using for last six month everything was working fine.
* Couple of TAC Case was open phone going to VM and user can't dial out.On-call manager everything was fine.
