Xenofon,
Thanks for looking into it, for sure I do use other advanced logic, it's
just a part of a script that I've found not working for me.
I'll try to make a lab that reproduce this behavior, but it will take
some time for sure. Why I pinpointed to this commit, it was about
"enclosing URI in <>" what is actually happening in my case, but a bit
incorrect.
I'll try to add some logs around commit code to see what exactly is
happening there.

Hey Ihor,
I can't seem to be able to reproduce this nor in master nor in 5.8.6.
My config is the default one with the following changes:
```
....
loadmodule "uac.so"
modparam("rr", "append_fromtag", 1)
...
request_route {
$avp(callerID) = "81982934";
xlog("Incoming request: $rm from $fu to $ru (IP:$si:$sp)\n");
xlog("callerID set to: $avp(callerID)\n");
uac_replace_from("sip:" + $avp(callerID) + "@localhost.localdomain");
// $fu = "sip:" + $avp(callerID) + "@localhost.localdomain"
// msg_apply_changes();
xlog("Modified request FROM: $fu\n"); // Not modifed beacuse we
didn't use msg_apply_changes();
t_relay("127.0.0.1", "5050"); // Should modify the FROM header
when forwarind as verified by sngrep
...
}
```
Crafting a message with you exact `From:
sip:[email protected];tag=83017fca-9fe4-493e-9e66-406034482628
<mailto:sip:[email protected];tag=83017fca-9fe4-493e-9e66-406034482628>`
produces From:
sip:[email protected];tag=83017fca-9fe4-493e-9e66-406034482628`
according to |sngrep| and inspecting the headers.
Relevant logs:
*ERROR*: {1 2 INVITE a84b4c76e66711} <script>: Incoming request:
INVITE from sip:[email protected] to
sip:[email protected] (IP:127.0.0.1:42486)
*ERROR*: {1 2 INVITE a84b4c76e66711} <script>: callerID set to: 81982934
*ERROR*: {1 2 INVITE a84b4c76e66711} <script>: Modified request FROM:
sip:[email protected]
Do you perform some other advanced logic or use some modparams that
might have modified this behavior?
Thanks,
Xenofon

A bit update:
uac_replace_from() behave the same way as assigning to $fu (measn
incorrect), and I confirm it on 5.8.5 and onwards (for the moment).
So, somewhere between 5.8.4 and 5.8.5 this regression was introduced.

Daniel,
That's the thing, if I comment out just this string, there is
no such behavoir.
I will look at uac_replace_from(), but assigning $fu is quite
a basic operation and is ok in a previous version. I've
checked, there is no double changes to $f... family of
variables and no msg_apply_changes() in between. And yes, $fu
is changed before creating a transaction.
I'll dig more in the code to see what can cause this, but my
message was maybe just a warning to community, that transition
from 5.8.4 to 5.8.6 might be not flawless,
Cheers,
Ihor

I don't recall changes on this during the same release
series, normally you should use assignments to $fu in a
very careful way, recommended way is with
uac_replace_from(). You have to check you config and be
sure you do not make changes over From-URI twice or more,
or try to use msg_apply_changes() if you do it in
request_route before the transaction in created.
Cheers,
Daniel

Not sure where the bug is, just noticed when playing
on local development Kamailio installation, that
simple rewrite of $fu start to act funky.
Initial From field in a packet is:
From:
sip:[email protected];tag=83017fca-9fe4-493e-9e66-406034482628
<mailto:sip:[email protected];tag=83017fca-9fe4-493e-9e66-406034482628>
In the code I'm having a statement
$fu = "sip:" + $avp(callerID) + "@localhost.localdomain";
Resulting From field on 5.8.4 looks like
From:
sip:[email protected];tag=83017fca-9fe4-493e-9e66-406034482628
<mailto:sip:[email protected];tag=83017fca-9fe4-493e-9e66-406034482628>
Note the 2 spaces after From, but it's ok, I guess, no
other changes which is fine.
But exact the same config file on 5.8.6 giving this:
From: <sip:[email protected]>
<mailto:sip:[email protected]>sip:[email protected];tag=83017fca-9fe4-493e-9e66-406034482628
<mailto:sip:[email protected];tag=83017fca-9fe4-493e-9e66-406034482628>
Which is not correct SIP URI. I'm not sure when the
issue was introduced, but that's what I've found. If
will have a bit more time, will try to investigate
deeper, maybe just to warn about possible bugs with
the versions greater than 5.8.4 (have not tested 5.8.5)
