Whenever we restart asterisk many of our phones can’t register anymore.
If I sniff the interface on the asterisk box I see this with ngrep.

Content-Length: 0.Nothing shows up w/ “sip debug”. There is no response from asterisk either. I can ping the phone from the asterisk box just fine.
This is my sip.conf:
[126]
type=friend
secret=xxxxxxxxx
record_out=On-Demand
record_in=On-Demand
qualify=yes
port=5060
pickupgroup=
nat=yes
mailbox=126@device

dtmfmode=auto
dial=SIP/126
context=from-internal
canreinvite=no
callgroup=
callerid=Jo Bob <126>
accountcode=
call-limit=50
Any ideas?
