Daniel,
I did do a check and "" quotes are printing in xlog for $fn.
can you send the sip trace for such case? I tested with options and ""
is removed.
Cheers,
Daniel
Thanks!

Daniel,
So if I am to set it to "none" it should give me the desired
affects, and not alter back to the original From header upon
transmission of an ACK?
auto mode should do everything (update/restore From (or To)) for
within dialog requests, if you used uac_replace_from() for initial
INVITE, therefore this is the best mode. However, it adds an extra
parameter (pretty long) to RR header and some UA strips it when
building the reply.
If you know you are in a SIP2.0 (rfc3261) compatible environment,
then you can use other modes.
In sip 2.0 a dialog is identified by call-id, from-tag and to-tag,
which are not affected by From updates. However, in previous
version of sip, From URI and To URI were used to identify the sip
dialog, therefore, in order to be compatible with sip 1.0 then you
should not change From/To.
In auto mode, the From/To are restored to be safe with sip 1.0
devices.
Btw, if you have time, can you please print the $fn in xlog for
ACK and send it here? Will show if quotes are considered part of
display name. If not, I will look later in sources.
Cheers,
Daniel

Value of uac_restore_mode is not set so "auto".
but if it is not set to something else, this is the default
value.

Daniel,
This is 1.5 and there is nothing between the quotes "".
the question is whether the display name attribute in
From header structure includes the quotes or not -- this
is to be revealed by code.
The last time I tried to remove_hf, and then
append_hf(From) or To header, it seemed to break call
flow completely?
It can break in case you have non-RFC3261 compliant devices.
What is the value of uac module parameter from_restore_mode?
If it is auto or not set, then it is not the same
behavior as with remove_hf/append_hf.
I will give it another go, however if you have any
further thoughts it is much appreciated, thanks!
Going to check the sources and come back with more details.
Cheers,
Daniel

Hello,
As always thank you ahead of time for your help
and input!
I am currently calling uac_replace_from("", "")
in effort to "leave uri" and "toss away display
name"
Which does seem to work....... for the initial
INVITE
However upon receiving an ACK with an empty
display, however "" <- quotations, it does not
clear the display "" which is causing issues
with one of my upstream vendors.
Example / Scenario:
From: "" <sip:u...@host>
Expected Result upon uac_replace_from("",""):
From: <sip:u...@host>
Current Result: From: "" <sip:u...@host>
As you can see it is not stripping the "" empty
display quotes.
Any thoughts / ideas / suggestions to get my
desired affect?
could be that display name is set to empty string
(what is between double quotes) and in this case is
nothing to replace -- I have to doublecheck the
sources. Is it 1.5 or 3.0?
Are you using From auto-replacing mode? If not, a
solution for now is to do From update using header
manipulation functions:
remove_hf("From");
append_hf("From: <$fu>;tag=$ft\r\n", "From");
Cheers,
Daniel
