Error when Registering Trunk

[killmasta93]

Hi,
I was wondering if someone could help me out registering my Grandstream gateway HT701(192.168.3.5) to my elastix(192.168.3.252). I have been searching though google,bing on guides and stuff and I have partially configured but for some reason on the webGui on the grandstream shows unregistered while on Elastix when i type sip show peers it shows that its connected but when I run putty and check for errors it shows that cannot register see pictures.

Thank you
