Hi,
I've been looking at ser for a couple of days now and there some things I
can't find in the documentation.
.1. Logging funktionality
I'm used to being able to log more detail than what I can get out
ser. I'm problably missing something in the documentation, but
what I want is something like the following
timestamp ser[pid] Incoming packet from ip:port
[dump of packet (only the sip header/body)]
timestamp ser[pid] Invite from [] to []
timestamp ser[pid] After rewrite: from [] to []
timestamp ser[pid] Relaying packet to [pstn-gw/other sip server]
/
timestamp ser[pid] Handling request for local user []
Can you send arguments to the log() function in the configuration
file for example log(1,"Call from %s", uri:from); ??
.2. Rewrite rules
Is it possible to rewrite the from uri?
For example when I [sip:tomas@krixor.xy.org] want to call a pstn
number I must rewrite the from address to
[sip:myphonenumber@krixor.xy.org] before I send the request to
the pstn gateway
And when a incoming call comes from the pstn gateway I want to
rewrite the from address from [<sip:number@ip-of-pstn-gateway>]
to {"PSTN Luser" <sip:number@pstn-gw.mydomain.com>]
I haven't looked at the source in the CVS yet, but I aim to do so soon, I
saw in the list archive that you have lots of nice new features planned
for the next release. ENUM support is one of the better ones :)
Anyway, looking forward to trying to help with the development of this
software.
Best regards,
Thomas Björklund

We would like to have that too. We've been thinking of
log("hello world: method=%m, src_ip=%s"). Unfortunately,
it will not show up in the upcoming release, since we are
simply too busy with making too many other changes. I would
wish to have it in the overnext release.

That is quite tricky -- it is close to protocol breaking. The From header
field has been designed read-only in SIP. Nevertheless, this application
has been already asked for. I wrote a short text on how to do that for
those who wish to do so.

ENUM is on CVS, if you have courage to play with CVS code and problems
occur we will be glad to help :-)

Great. I don't think that you should break the protol, but in this case it
really doesn't matter cause I'm the only one receiving the request :)
I tried to install the cvs version and first off it failed to compile due
to pass_fd.c (support for TCP) so after disabling -DUSE_TCP in the
makefile it compiled ok, but when I start it I get the following error:

This is on a OpenBSD 3.1 with gcc version 2.95.3
Also, It's pretty annoying that 'gmake install' overwrites the
configuration file all the time :)

Thanks for the patch. Maxim already included a fix for this in his
patches (that were for a long time in my pending patch list :-)).
The CVS version is patched.

Got it working 'kinda', the problem is not to change the From: adress but
to actually change it back when sending messages to the originating UA.
Do you have any example configuration for SER to do this? It looks like
you've done som testing in the area ? This is a feature
many people (anyone with a pstn-gateway) could use.
Something like a './serctl enum add phonenumber sip-user[(a)domain.com]'
that gets added to the sql database would be nice.
And a flag(X) to trigger the translation if the invite is coming
from/going to the pstn gateway.

From in requests would have to be rewritten, From in replies for these
requests too, To in subsequent requests (and associated replies) from
the other party too.

Unfortunately not -- that is a piece of work which would have to be
implemented. We can provide guidance but have currently no cycles to
do it ourselves. It is actually not such a big deal but all of us are
now burdened with the upcoming ser release.
Something like a './serctl enum add phonenumber
sip-user[(a)domain.com]'
that gets added to the sql database would be nice.
Getting the aliases in the database is trivial part. Transaction rewriting
is the major piece of work.
