cisco 79XX issue, new config, all good but no inbound

I had this working earlier and it stopped. No idea which of the millions of config options I screwed up so a bit of a hint would be very welcome. I register with the server just fine, I am able to dial out, but can't dial back in. When I do call back in, a DEBUG SIP-MESS.. shows this: (what looks odd to me is that sometimes the URI shows 16... sometimes just 6.... I left the numbers identifiable while masking so you can see what I mean). Please help!

Code:
