[Dennis]

I am using asterisk 12.1.0 in centos 6.5, follow the link:?https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+Installation+and+Configuration?
I completed the installation and the configuration, tested two sip phones to call each other,everything working fine. Then i used asterisk to register with china telecom ims server, the IMSreturn a 400 ?Bad request, the sip debug below:

（I used xxxxxx to replace the informations）
The key problem is "Register request having user info", and asterisk 12 don't include the "INFO" sip request in Allow header,I have tested this IMS account in asterisk 1.8.20, it working normal, so i just want to know the problem which i faced is a bugor a config problem, thanks for any advice.
