Asterisk 11.7.0 MGCP Register failed

I use a gateway to register to asterisk but failed.
HUAWEI U-SYS iad101h
That is my settings:
mgcp.conf:
[general]
port=2427
bindaddr=0.0.0.0
[iad101h1]
context=iad101h
host=dynamic
callerid=“169”<169>
nat=yes
dtmfmode=rfc2833
canreinvite=yes
line=>aaln/0

I can’t register on asterisk , what is wrong?
I can successful register two sip phone.
The gateway keep sending register package to asterisk.

Is asterisk-11.7.0 doesn’t support MGCP ? ( Need to download patch)
