5.Check the phone got ip address.

6.In CCM phone status is unknown.

Thanks in advance for all your inputs.Thanks.


Re: 7970G Security Error


Do you have the following service enabled in control centre?:

Cisco Certificate Authority Proxy Function service

If you check another phone in the office that is already working, does it have an LSC (Locally Significant Certificate)? You can check this by going to Settings > Model Information (4)

What version of CCM are you using??

Please rate useful posts...

Thanks for the input.

LSC not installed as compare to the working 1.It should be fine.

CCM version

Communication from phone to CCM seems ok but somehow can't get registered.

Hi,manage to solve the problem finally.

It was caused by firewall blocked port 3084/tcp.

I enabled udp for the cisco recommendation ports,it seems like it needs tcp to be allowed as well??


Re: 7970G Security Error

Yes, do you mean 3804/TCP? 5* for figuring it out..
