Hi Federico,
1. Do you use "consume_credentials()" function in first place?
I repeat: this function removes Authorization header fields after using
them.
It can give you more than 200 bytes of margin in typical situation. It is
more than enough. What's more, you don't usually want to expose details of
your authorization
mechanism to outside world. Although we are talking about Digest
authorization scheme, it is still interesting for malicious user to know how
do you perform authorization and what are digest user names....
2. IMHO e, converting header field names to abbreviated form is actually
<more> traumatic, than editing SDP.
I rarely see UAs that use abbreviated form of SIP header fields.

OK, but what about the idea of rewriting all header
field names using
the compact form?
It seems to me less traumatic than altering the SDP data.
Are there C functions in SER that replace a header name (and only the
name, not the value) with a different one?
Alternatively, are there C functions to find the pointer to the header
field with a given name, delete it and insert a new one?
Thanks.
