[Asterisk-Users] Cisco 7970 startup problem

[Parfenenok Sergey]

Hello all.

I have a problem with Cisco 7970. At startup this device asks for CTL 
(Certificate Trust List) file,
and startup process stops. I am even can't boot this device. Does anyone 
know how to avoid this problem?
It is said that in older versions of SCCP dummy file with the name 
CTLSEP<mac addr>.tlv placed
to TFTP can solve this problem, but in newer versions it doesn't work.

Please help!
