Trunks suddenly became unreachable

[ghurty]

My box suddenly cant reach any of the three trunks, all of them are showing in the logs as unreachable.

However, I can ping out from the box to a website without a problem.

I tried restarted but it does not help.

A loss of DNS to the PBX will cause this. I usually run bind on my pbx's for that reason.

I am able to ping "sipgate.com" from the pbx.

Thanks
