Hi,
I can't see that you have done anything wrong.
>From the SIP grammar, the display-name is:
display-name = *(token LWS)/ quoted-string
And, in your case, you have a quoted-string:
A string of text is parsed as a single word if it is quoted using
double-quote marks. In quoted strings, quotation marks (") and
backslashes (\) need to be escaped.
It seems that you have escaped the backslash.
The only thing is, I can't see where it says how to escape
things in the quoted-strings. I assume that your use of the backslash
to do the escape is correct but I'm not sure.

Maybe you could try adding a space after the second
double-quote - I have heard that some implementations
don't like it if there is no space (even though the
lack of ' ' is actually legal).
Regards,
Attila
