Are your network settings correct or is that a typo?

"We have a 10.10.0.0 internal network. The asterisk server - 10.10.10.180"

...which tells me your mask should probably be 255.255.0.0.

BUT, in the phone config, you have the mask as 255.255.255.0.

This might not tbe cause and 'be-all end-all' of your issues, but it's worth some attention.
