Trunk registration fail

Hi,
I have a problem with the trunk registration on my asterisk.
I have Asterisk 11.4.0 version and I use freepbx 2.11.0

This trunk worked but I maybe changed some configuration because the sip show registry show me that he is not registered. This is my configuration on freepbx, I have the same configuration on an other server and that works, and If I try to register the sip account directly on a softphone it also works.

host=freephonie.net
username=mynumber
secret=mysecret
type=peer
qualify=yes
fromdomain=freephonie.net
dtmfmode=auto
context=from-trunk
disallow=all
allow=ulaw&alaw
canreinvite=no

Register String
mynumber:[email protected]phonie.net

I only add on the sip configuration settings defaultexpiry = 1800, that is required for my provider.

this is the output of the sip debug when I try to start a call
