Hey, anybody had the problem that they get : Calling (Out INV) when trying to call out trugh a cisco 7960 ? Iv got 2 phones, with the same config. only diff, one between NAt and one connected to the internet with nothing between. the one that's behind NAT is working perfect. but the one thats got a bare internet link gets the Calling (Out INV) error. It does send a invite... so the other phone starts ringing.. but nothing more. I do get incoming on the phone.. and that works like a dream. - Atle
