I just received Cisco 9971 (I had previously 7950) and looks like it doesn’t want to work at all.
I have tested 8 different XML config files, from every site/forum that I was able to find.
Unfortunately always I am getting Error Verifying Config Info (file name correct, firmware version updated, Elastix with enabled TPC, extension also changed to TCP).
What is more scarying is that this phone keeps looking for TVL files and won’t upgrade / downgrade to any other firmware (with 7950 I just had to change firmware version in info line and here is nothing).
Is it maybe because in Admin Settings -> Security -> Trust List -> there is (signed) next to Configuration ??
I have found info that TLV are some extra security files.
Is this phone dead end ?
Is there any way to remove need of searching for TLV files, update firmware and sign up with my Asterisk server ?
