The display name was removed because you had configured a caller alias.
You can tell because the Record-Route header has a fromalias attribute
in it - this can be decoded using the sipx-readroute script:
sipx-readroute
Record-Route:
<sip:192.168.5.240:5060;lr;sipXecs-rs=%2Afrom%7EZHJqdzZvcnB6bQ%60%60.400_authrules%2Aauth%7E.700_fromalias%2Aalias%7EPHNpcDo3MzItMzIwLTQyODBAZXhhbXBsZS5jb20%27O3RhZz1kcmp3Nm9ycHpt.700_fromalias%2Acaller%7EInVzZXIgc2l4IiA8c2lwOnVzZXI2QGV4YW1wbGUuY29tPjt0YWc9ZHJqdzZvcnB6bQ%60%60%21c7c2d612599987c01f743df2b1f6a0e3>

700_fromalias*alias=<sip:[EMAIL PROTECTED]>;tag=drjw6orpzm
700_fromalias*caller="user six" <sip:[EMAIL PROTECTED]>;tag=drjw6orpzm
The 'caller' attribute is the original caller url, and the 'alias'
attribute is the value it is replaced by.
The CallerAlias authplugin takes the value from its IMDB table and uses
it as a full url, replacing only the 'tag' value.
Apparently, sipXconfig won't let you enter a full URL value in the
alias, but if it would, then you could control any part of the url sent
in the aliased call except the From tag.
