[Asterisk-bugs] bug in sip header? (sip from address)

[Glo]

Hello,
i´ve already posted this question in "asterisk-general-forum" and I´ve 
no answer,
so i think it could be a bug.

Please, let me know if this behavior happens to you.If you want to test it
you can send me a email.

When I use the ${SIP_HEADER(FROM)} function, I get the rigth "sip from 
address", but when the message reaches the client this "sip from 
address" is incorrect

Thanks in advance
