Prb no transport of text/plain as Content-Type in INVITE

Hi,

I am tying to send an INVITE with a Content-Type of text/plain from user 1 to user 2. Asterisk does not transport the Content-Type and Body of the INVITE to user 2.

Is this a configuration problem or a missing feature?

User 1 sends:

INVITE sip:712@10.20.2.57 SIP/2.0
Via: SIP/2.0/TCP 10.20.3.90:5260;branch=z9hG4bK.369E103BE8354E35710346B86FD59DB9

some tests

User 2 gets:
